TAS2110EVM: Unable to play .wav file with STM32U5 + TAS2110EVM (Getting noise/corrupted audio)

Jinal Ubhatar

Part Number: TAS2110EVM
Other Parts Discussed in Thread: TAS2110

Tool/software:

Hello,

I am trying to play a .wav file using an STM32U5 microcontroller with the TAS2110EVM amplifier board, but I am only getting noise or corrupted audio output.

Hardware Setup:

STM32U5 MCU (using SAI peripheral for I²S audio)
TAS2110EVM board
External 5V / 3A power supply for TAS2110EVM
Connected pins:
- FSYNC, SCLK (SBCK), SDIN → to TAS2110 for I²S
- SDA, SCL → I²C control interface
External speaker connected to TAS2110EVM
Checked SDZ pin → voltage is 1.8V (so device seems enabled)

Issue:

WAV parsing works fine.
TAS2110 initialization (via I²C) is successful.
Playback via HAL_SAI_Transmit_DMA() produces only noise/corrupted audio instead of the WAV file.

SAI Configuration:

hsai_BlockA1.Instance = SAI1_Block_A;
hsai_BlockA1.Init.AudioMode = SAI_MODEMASTER_TX;
hsai_BlockA1.Init.Synchro = SAI_ASYNCHRONOUS;
hsai_BlockA1.Init.Protocol = SAI_FREE_PROTOCOL;
hsai_BlockA1.Init.DataSize = SAI_DATASIZE_16;
hsai_BlockA1.Init.FirstBit = SAI_FIRSTBIT_MSB;
hsai_BlockA1.Init.ClockStrobing = SAI_CLOCKSTROBING_FALLINGEDGE;
hsai_BlockA1.Init.OutputDrive = SAI_OUTPUTDRIVE_ENABLE;
hsai_BlockA1.Init.NoDivider = SAI_MASTERDIVIDER_ENABLE;
hsai_BlockA1.Init.FIFOThreshold = SAI_FIFOTHRESHOLD_1QF;
hsai_BlockA1.Init.AudioFrequency = SAI_AUDIO_FREQUENCY_44K;
hsai_BlockA1.Init.SynchroExt = SAI_SYNCEXT_DISABLE;
hsai_BlockA1.Init.MckOutput = SAI_MCK_OUTPUT_DISABLE;
hsai_BlockA1.Init.MonoStereoMode = SAI_MONOMODE;
hsai_BlockA1.Init.CompandingMode = SAI_NOCOMPANDING;
hsai_BlockA1.Init.TriState = SAI_OUTPUT_NOTRELEASED;

Example code:

if (tas2110_init(&tas_data) != 0) {
HAL_UART_Transmit(&huart1, (uint8_t*)"TAS2110 Init Failed\n", 20, 100);
Error_Handler();
}
tas2110_set_samplerate(&tas_data, wav_info.sample_rate);
tas2110_set_bitwidth(&tas_data, wav_info.bits_per_sample);
tas2110_set_dai_fmt(&tas_data, 0x0020);
tas2110_set_dai_tdm_slot(&tas_data, 1, 0, 1, wav_info.bits_per_sample);
tas2110_set_volume(&tas_data, 84);
TAS2110_ReadDVC(&tas_data);
tas2110_power_on(&tas_data);
tas2110_mute(&tas_data, false);

// Test tone
for (int i = 0; i < AUDIO_BUFFER_SIZE; i++) {
audio_buffer[i] = (int16_t)(3276 * sinf(2 * M_PI * 1000 * i / 44100.0f)); // Low amplitude
}
HAL_SAI_Transmit_DMA(&hsai_BlockA1, (uint8_t*)audio_buffer, AUDIO_BUFFER_SIZE);

Question:

Is there any specific I²S format requirement for TAS2110 (e.g., word length / frame sync polarity / slot config)?
Do I need to use MCLK along with BCLK/LRCLK/SDIN, or can TAS2110 derive clock internally?
Could this be related to mono vs stereo configuration?

Any guidance on correct I²S + TAS2110 configuration or pointers to a working reference would be very helpful.

Thanks in advance!

Hi Jinal,

You should set registers 0x06 through 0x09 according to the host processor configuration.
I2S is usually using RX_OFFSET of 1. You can try changing some other settings such as RX_EDGE and FRAME_START to check if they have any improvement.
MCLK is not used, just need to provide BCLK and WCLK.
Are you sending data on both channels from the host? On TAS2110 you can select to play the data on either channel or combine them based on RX_SCFG and RX_SLOT_R and RX_SLOT_L

Hi Ivan,
Thanks for response.
I have already configured registers 0x06 through 0x09 according to the host processor setup.

My register write sequence is as follows:
tas_write_reg(tas2110_data_t *tas, uint8_t page, uint8_t reg, uint8_t val) {
uint8_t buf[2];

// Set page
buf[0] = 0x00; //TAS2110_PAGE_CTRL;
buf[1] = page;
HAL_I2C_Master_Transmit(tas->hi2c, tas->dev_addr, buf, sizeof(buf), HAL_MAX_DELAY);

// Write register value
buf[0] = reg;
buf[1] = val;
HAL_I2C_Master_Transmit(tas->hi2c, tas->dev_addr, buf, sizeof(buf), HAL_MAX_DELAY);
}

My initial configuration looks like this:
tas_write_reg(tas, 0, 0x01, 0x01); // Reset
HAL_Delay(10); // Short delay after reset

// Set default power to shutdown
tas_write_reg(tas, 0, 0x02, 0x02);

// Default TDM / I2S config
tas_write_reg(tas, 0, 0x06, 0x09);
tas_write_reg(tas, 0, 0x07, 0x02);
tas_write_reg(tas, 0, 0x03, 0x20);

I am currently sending mono audio data from the host.
Could you please suggest if I am missing any additional configuration (for RX_OFFSET, RX_EDGE, FRAME_START, or channel routing using RX_SCFG, RX_SLOT_R, RX_SLOT_L)?

Thanks,
Jinal

Hi Jinal,

Can you please try playing a low amplitude sine tone, you can do 1kHz at -16dBFS, the resulting signal should be 1Vrms at the speaker.
Then you can record the resulting sound, if the audio is not noisy try the same for a few increasing dBFS levels.

Please share the recordings so we can analyze and understand if this is clipping kind of noise or some random distortion which can point to incorrect format settings.

Hi Ivan Salazar

Thanks for your response.
I am now able to get the actual sound, but it is noisy. Could you please suggest the possible reasons for the noise?

Could this be related to the configuration?

For reference, I have connected a common ground between the EVK board and my STM32 board.

Do you get noisy audio only after certain volume level?

I'll have to circle back to my previous suggestions:

Hi,
I’m still getting noise at all volume levels.

As per your suggestion, I tried using a sine wave audio file, but the noise persists in that as well.
I’ve attached both the recorded and the original sine wave audio files for your reference.

Please let me know if any register updates or configuration changes are required.

Also, when I play audio using the board’s MCU (XMOS), the output is almost proper.
Could you please suggest what configuration might be missing?
If possible, could you share the XMOS and TAS2110 configuration details?

You can use PPC3 to get the TAS2110 configuration, this is an example for default settings in CFG and H formats. You must add the power up command for register 0x02 at the end of the script.

XMOS works in TDM 8CH format by default. SBCLK = 12.288MHz, FSYNC = 48kHz.

I would suggest checking your host clocks, make sure the frequency of these clocks is correct and stable.

You can use the Auto Detect features on registers 0x06 for Sample Rate Auto Detect and register 0x38 for SBCLK to FSYNC Ratio Auto Detect.

Hi,

Thanks for your response.

We captured the audio waveform using both the EVK board (with XMOS MCU) and our external setup based on STM32U5. We noticed that the waveforms are quite different, even though the same input audio data is used in both cases.

Could you please suggest what might be causing this behavior?
Is it possible that the noisy audio is related to the clock or FSYNC signal integrity or alignment?

Additionally, we are configuring the sample rate using register 0x06, but we couldn’t find any details about register 0x38 in the datasheet (Copyright © 2019, Texas Instruments Incorporated – Submit Documentation Feedback).

Please find attached the captured waveforms for both the EVK and STM32 setups.

Thanks,
Jinal

Hello,

Are you using the same script on both devices? One thing you can try is bridging the I2S pins from the EVM to your board and see if the output matches the EVM. Then we can confirm if audio input is the issue. We'll also review the captures in parallel.

Regards,

Hi,

I am connecting the I²S pins from the EVM to our MCU board in the same way. However, it seems that the XMOS MCU on the EVM is operating in TDM mode, while our STM32 MCU is configured for I²S protocol.

Could you please suggest the correct configuration required for the I²S protocol to ensure proper audio playback with the TAS2110?

For more details, please refer to the attached waveform captures.

Thank you

Hi,

Is it possible to play audio using the I²S protocol through the PPC3 tool?
Currently, it seems that the TAS2110 operates in TDM mode during audio playback.

Have you had a chance to review the waveform I shared earlier?

Thanks,

Hi Jinal,

Apologies for the delayed response, both Ivan/Sydney are out of office.

Currently you cannot play audio using I2S through PPC3, but you can connect the STM32 I2S signals to the TAS2110 which supports I2S.

Let me catch up on the rest of this post and I will provide more feedback as soon as possible.

Regards,

Sebastian

Hi Jinal,

I2S is essentially TDM with an offset of 1 and I believe the XMOS is operating in I2S mode. In PPC3 you can deselect "Use USB Audio settings" and the TDM box will un gray out so you can alter the settings. It is grayed out because with USB audio settings selected it auto configures to be compatible with the XMOS settings.

To confirm though, on the EVM and your custom board you used the same I2C script. For this test, you bridged the I2S from the EVM to the custom board and then ran the custom script. What was the result when you played audio data?

Regards,
Sydney Northcutt

Hi Sydney Northcutt

Have you had a chance to review the waveform?
It would be helpful if you could take a look at the captured waveforms from the EVK and the bridged STM32 board, as your observations might help us identify the issue.

Thanks,

Jinal

Hello,

I do not notice anything incorrect with the waveforms from looking at them, but what was the result when jumping the I2S from the EVM to your board? Was the noise issue still present?

Hi,

Could you please suggest what configuration changes are required to modify the setup from TDM mode to I²S communication?

We would like to change the ratio of SCLK to FSYNC; however, it appears to be fixed in the PPC3 tool. Is there any way to modify this ratio? We want to set it to 128.

Thanks,

Jinal

Hi,

When bridging the I²S lines from the EVM to our board, the noise issue is still present. In this setup, the XMOS configuration is used while the audio data is played from the STM32.

If the waveform looks fine, what could be the reason we’re getting noise with I²S (STM32) while the audio is clear with TDM (XMOS)? Is there any specific cause for this difference?

Could you please suggest the possible areas or steps we should check to identify the source of the noise or distortion issue?

Thanks,
Jinal

Hi Jinal,

What is your word length and slot length configuration?
You mentioned ratio of 128 is needed, but I2S format is 2 channels only. Perhaps you're actually using ratio of 64? Being 2 channels of 32bit each?
One more thing you can test with is the Receiver Offset changing from 0 to 1, or the Edge Polarity changing from Rising to Falling, or the Frame Start Polarity also changing from Falling to Rising.

You can specify these values so I can check using Audio Precision and EVM to get a PPC3 configuration:

Format: As I understand it should be standard I2S
No of channels: Normally I2S is Left and Right only, please let me know otherwise.
Slot length: 16, 24 or 32 bits
Word length: 16, 20, 24 or 32 bits
SBCLK frequency
FSYNC frequency (these frequency values help verify the clock ratio)

Best regards,

Hi Ivan Salazar

Our current STM32 configuration is as follows:

Slot length: 16 bits
Word length: 16 bits
SBCLK frequency: 3 MHz
FSYNC frequency: 48 kHz

Please find the relevant SAI configuration snippet below:

hsai_BlockA1.Instance = SAI1_Block_A;

hsai_BlockA1.Init.AudioMode = SAI_MODEMASTER_TX;

hsai_BlockA1.Init.Synchro = SAI_ASYNCHRONOUS;

hsai_BlockA1.Init.OutputDrive = SAI_OUTPUTDRIVE_DISABLE;

hsai_BlockA1.Init.NoDivider = SAI_MASTERDIVIDER_ENABLE;

hsai_BlockA1.Init.FIFOThreshold = SAI_FIFOTHRESHOLD_EMPTY;

hsai_BlockA1.Init.AudioFrequency = SAI_AUDIO_FREQUENCY_48K;

hsai_BlockA1.Init.SynchroExt = SAI_SYNCEXT_DISABLE;

hsai_BlockA1.Init.MckOutput = SAI_MCK_OUTPUT_DISABLE;

hsai_BlockA1.Init.MonoStereoMode = SAI_STEREOMODE;

hsai_BlockA1.Init.CompandingMode = SAI_NOCOMPANDING;

hsai_BlockA1.Init.TriState = SAI_OUTPUT_NOTRELEASED;

if (HAL_SAI_InitProtocol(&hsai_BlockA1, SAI_I2S_STANDARD, SAI_PROTOCOL_DATASIZE_16BIT, 4) != HAL_OK)

Please let me know if you need any additional information.

Kindly take a look at the waveform with a 64x ratio — we’ve observed that the frequency occasionally behaves unexpectedly. Could this be related to the noise issue we’re facing?

Would it be possible to schedule a remote debug session to help analyze the configuration and identify the root cause of the noise issue?

Thanks,
Jinal

I tested with the following input clock settings:

I only connect SBCLK = 3.072MHz, FSYNC = 48kHz and SDIN to the EVM. MCLK remains disconnected.

Attached is a PPC3 configuration I used to test on EVM.

https://e2e.ti.com/cfs-file/__key/communityserver-discussions-components-files/6/TAS2110_5F00_48k_5F00_64ratio_5F00_16dBV.ppc3

Also below is the configuration script generated using the same PPC3 configuration.

The EVM is working OK with these settings, as a simple test I feed -16dBFS signal which produces 1Vrms output signal.

If you suspect the input clocks may be a problem, you can try tapping the input clocks to TAS2110 and use AP or another known good clock source to connect directly.

Hi Ivan Salazar

Based on the audio analyzer results, the ratio appears to be 256, whereas in our setup it is 64.
According to the TAS2110 datasheet, page 0, register 0x11 is marked as read-only, but we noticed that PPC3 is writing to this register — could you please clarify why?
We have tested using the latest PPC3 configuration provided, but the issue still persists.
We have also shared the audio analyzer data captured from the MCU-side configuration for your review.
Please find the attached audio files for reference.
Would it be possible to schedule a remote debug session to help analyze the configuration and identify the root cause of this issue?

Thanks,

Jinal

Hi Ivan Salazar

You can review the debug data shared above and suggest where the issue might be occurring.

We would also like to request a remote debug session to help expedite the investigation and resolve the problem quickly. We’ve been stuck on this issue for the past three weeks and are unable to make further progress. Please let us know a suitable time for you to connect — we are in the IST time zone.

We appreciate you're understanding and support on this matter.

Thank you,

Jinal

The ratio of 256 on my AP capture is for MCLK, as mentioned this is not used as MCLK pin is left floating. The ratio for SBCLK is given by Word Width times Number of Channels = 16 * 4 = 64.

Page 0 Register 0x11 will update automatically once the device is enabled and the Sample Rate Auto Detect feature is active. Writing to this register is unnecessary but it should not affect the device operation.

The SBCLK to FSYNC Auto Detect feature is disabled by default, the ratio is set by Page 0 Register 0x38. It has been set to 64 for the provided PPC3 configuration file.

One more thing we could try is disabling the Sample Rate Audo Detect feature and set a fixed value of 48kHz. Attached below is the PPC3 and the corresponding configuration script.
