Linux/TAS6424L-Q1: TAS6424 ALSA issues

user4365218

Part Number: TAS6424L-Q1
Other Parts Discussed in Thread: TAS6424, TAS6424-Q1

Tool/software: Linux

We are trying to use the TAS6424Q1 with the beaglebone green wireless (am335 CPU) to get an audio interface.

We compiled the linux module (proposed in https://patchwork.kernel.org/patch/9792087/) and add the necessary nodes to the DTS. But we don't see the TAS6424 as sound card in Alsamixer.

Did anyone succeed in getting the TAS6424 appear as sound card on alsamixer so you can control the volume?

Best regards

Hi Mohmed-Amjad,

I'm the applications engineer for TAS6424.

TAS6424 is an audio amplifier. It does not have direct interface to wireless device. It has I2C (low level device register settings) and I2S (low level audio bus with clocks and data). Any interfaces to higher module such as USB, wireless or Bluetooth will have to be done in that specific drivers.

Hopefully someone on this forum who is more familiar with beaglebone wireless can help with such a driver.

Best regards,

Tuan

Hi Tuan,

We are not trying to use the TAS6424-Q1 through the Bluetooth or Wifi. We want just to get volume/features control through alsamixer in linux . We found the TI linux module patch (refer to my question). but we can't get the control of the TAS6424 through alsamixer and it doesn't appear as sound card when I use the aplay -L command.

Thank you in advance for your answer
