[alsa-devel] Status of USB audio class 2 drivers in ALSA

I am working on building a multi-channel USB audio device using the PIC32MX2 series with dual WM8731 audio codecs. The goal is a low cost 4 channel USB audio device. While this might not be the best combination for multi-channel audio, I do not have a better solution as the XMOS series is not easily available in India. I would like to know the status of USB audio class 2 support in ALSA and is there anyway I can contribute. I did go through the USB specifications for audio class 2 devices, but an idea of the implementation in ALSA would help in writing the firmware.

Regards,

Anand
