SK-AM62P-LP: Audio Playback Issue via Bluetooth on SK-AM62Px-LP

Part Number: SK-AM62P-LP
Other Parts Discussed in Thread: M2-CC3351

Tool/software:

Hi,

I’m currently working with the following setup:

  • PSDK Version: ti-processor-sdk-linux-am62pxx-evm-10.01.10.04

  • Board: SK-AM62Px-LP

  • Audio Codec Module: TLV320AIC3106IRGZT

  • Bluetooth Module: EAR00388 (as recommended in the AM62Px User Guide, M.2 module)

I am trying to implement an audio system using Bluetooth. When I play a song from a mobile device, the audio is received, but only noise is heard through the headset jack. However, when I play a stored song sample rate (44.1 kHz, 16-bit), the sound is clear. The issue occurs only with Bluetooth playback, where noise is present instead of clear audio. The Bluetooth song sample rate is also the same

 Could you please advise how to fix this issue?

Veerapandiyan V.

  • Hi Veerapandiyan,

    Can you share the pipeline you are trying to validate the scenario? Are you using avdtpsrc to receive data from an A2DP device?

    What I understand from your query is a normal playback (Stored file on the EVM to Headset jack) is working fine.

    Understanding is correct.

    I need the patch file for the 2AE M.2 module. Please share the patch file, and I will check whether my configuration is correct or not.
