pcm device order change on boot. [Solved]

Postby KoO » 2020-05-27 11:45

With the below HDA-Intel and USB-Audio after most boots the order can change from 1 to 2. One boot HD-audio realtec is 1 next boot it can change to 2 and vice versa. I have seen this in the past with Debian even when I was using a USB dac. Is their away to stop this from happening. As it stuffs up my default sound device.
I have set alsa default sound device with sudo alsamixer. I do not use pulse audio only alsa.

Debian bullseye Linux debian 5.6.0-1-amd64 #1 SMP Debian 5.6.7-1 (2020-04-29) x86_64 GNU/Linux
Running mpd with ncmpcpp

HD-Audio = S1220A realtec hd audio
USB audio = neewer nw-7000 mic

Code: Select all
0 [HDMI           ]: HDA-Intel - HDA ATI HDMI
                      HDA ATI HDMI at 0xfcaa0000 irq 66
 1 [Generic        ]: HDA-Intel - HD-Audio Generic
                      HD-Audio Generic at 0xfc900000 irq 68
 2 [Device         ]: USB-Audio - USB PnP Audio Device
                      C-Media Electronics Inc. USB PnP Audio Device at usb-0000:09:00.3-2, full speed
