Hello All,

I have conencted a PCM2707C USB DAC to USB Port 2 on 12 pin header (Pins: 4 and 5). The USB DAC is recognized and can be seen in alsamixer.

In alsamixer, when I select the card 2 (USB DAC) and then escape out. After which I use command 'alsactl store' but the alsamixer defaults back to card 0.

I tried creating a asound.conf file using nano text editor in /proc/asound directory but was not able to. Got the error 'No such file or directory'

Any advice, what I can do differently. Please let me know if I can provide more information.

Thanking you.

Regards,
Vivek.
