In Debian 11 I have two users in a laptop Lenovo Ideapad S145.

One user has the sound working very well -- I don't know if it is a valid info but the user is in sudoers group. The other one gets Dummy Output in Sound Output Configurations.

Why one user gets audio and other doesn't, if the driver is installed and working properly for the first one?

Some possible relevant info (in console from the user sound is working):

Outuput of lcpci | grep -i audio:

00:1f.3 Audio device: Intel Corporation Ice Lake-LP Smart Sound Technology Audio Controller (rev 30)

Output of sudo lspci -nnk | grep -A2 Audio:

    Are both users in the audio group?

  • The problem was exactly that. The other user wasn't in audio group. If you want you can answer and I will approve. Thanks @currawong.

Ensure that all users are in the audio group in the /etc/group file.
