TLV320ADC5140: TVL320ADC5140 master + Raspberry Pi model 5 TDM 4 channels ,16bit, 48Kbit, 12.288 Mhz

Hi,

One of the things to look out for in the dts file when using more than 1 channel is your dai-tdm-slot-num, which you have set to 2 in the dts file you posted so it should work for 2 channels. What do your clocks look like? Are you giving the ADC BCLK and WCLK, or providing it just MCLK? What frequencies are these clocks? Also, can you check your asound.state file (you can generate one by running "alsactl --file ~/.config/asound.state store")?

Best,
Mir

Hi. 

still one channel(

MLCK is configured on AD9850 for 12.288 and connected to GPIO1  i2c_write 0x00 0x21 0xA0.  BCLK and WCLK  generated from codec. BCLK 1.536 (2ch*16*48000) or 3.072(4ch*16*48000).  WCLK 48 kHz. BCLK  and WCLK  from codec looking good and clean.  BCLK  and WCLK generation started from codec  after applying arecord commands and disappeared  after stop of arecord. 

here is asound.state. i do not know but alsactl --file ~/.config/asound.state store do not make file in this dir. i made it in temp

Hi.

Some update. Somehow i switched on second channel

i save config for all files for this case. if there is need i can show changes

Hi,

Yes what changes did you make? Is this 2 channels simultaneously? Are you able to use 4 channels yet?

-Mir

i lost this config(. what is done is total  working config  for RP4 for 2channels. i will try to move this config to rp5,

Ok, let me know if you need more help here.

hi Mir

sure

We need help. on RP5 we got only one ch working out of 2. and i need 4 channels

Man. look, wm8960 is perfectly working on rp5   

there is initially was also problem with kernel/ i took this repo from this branch and it start to work 

https://github.com/waveshareteam/WM8960-Audio-HAT/issues/68 

looking here for 2/4 dts, asound.cofig, asound.state

Hi Valerii,

Mir is out of office today. He will follow up with you tomorrow.

Thanks for your patience,
Jeff McPherson

hi Man.  here we got again that second channel switched on.  i saved config.

dts was muted

//simple-audio-card,mclk-fs = <256>;

Hi,

I think you may have more luck asking on the RPI forums about how to enable more than 1 channel on the software side. From my end, I would check what the clocks coming in/out of the device are, and check on a scope if you are seeing stereo I2S data or just 0s on the second channel. Let me know what you find there, and maybe mention what you find in the RPI forums if you go there.

Best,
Mir

Hi Man. Sure i will ask them. can i ask you for a favor? can you configure me 2 cfg files for 2 and 4 channels? Codec master 16 bit, 48kHz, 12.288 Mhz MLCK, AGC on, bias ti on, single ended.

Hi,

In the following link you can find a stereo audio recorder for RPI5 made with the ADC TLV320ADC6140
