Sound cards after kernel upgrade to 5.0

Since kernel was upgraded to 5.0, I have problems with selecting the default sound card:

% aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: MID [HDA Intel MID], device 0: ALC889A Analog [ALC889A Analog]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 0: MID [HDA Intel MID], device 1: ALC889A Digital [ALC889A Digital]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 1: HDMI [HDA ATI HDMI], device 3: HDMI 0 [HDMI 0]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

My system has a analog Intel sound card and a digital one with SP/DIF interface. I only want to use the analog one. But the default seems to switch between the digital and the analog one from boot to boot and even after suspend/standby.

How can I set the default sound card permanently to the analog device?

The ALSA name for both devices seems to be the same (MID) and the index is also the same. How can I distinguish between those two cards?

I can select the "correct" card in alsamixer using the ncurses interace (F6), but this doesn't change the selected card for pulseaudio and furthermore for KDE which I use.

Hi, Trilby
I also have this issue after recently updating.
But the weird thing is that I can solved the issue by unplug my device then plug again.

Here is some screen shot of pavucontrol

The screen before unplug device

The screen after unplug and plug

Here is some output of aplay command

Any idea about how to solve it. Thank you Gordon.

Re: Sound cards after kernel upgrade to 5.0

Hi, all
I have partly solved this issue, It's about the pulseaudio server default profile problems.
The sound server use wrong sound profile.
use

pactl set-card-profile 1 output:analog-stereo+input:analog-stereo

to set correct correct profile.
You can also add this to system wide profile refer to https://unix.stackexchange.com/question … pulseaudio

But why the default profile is wrong I have no idea.

Re: Sound cards after kernel upgrade to 5.0

I believe what Trilby is pointing to is that the order of the sound cards can change on every boot and so the sound indices can change.  It's probably best to configure /etc/modprobe.d/alsa-base.conf to make the sound card index persistent.
