Using a Dell Inspiron 5593; sound worked on R4.0 and R4.1 for over two years
After updating to R4.1.1, device’s sound output becomes unreliable–works in one VM but not another; sometimes works for a short while after restarting.
Next day, sound has become completely non-functional and a reinstall of pulseaudio-qubes did not help.
Pulseaudio mixer plugin in dom0 shows that sound is still being piped in from the VMs (channel volumes show change), but no amount of tweaking can revive sound on any output device.
One fix I’m trying is downgrading dom0’s kernel from 5.18. However, in R4.1 downgrading is no longer as simple as changing the contents of /boot/efi/EFI/qubes/xen.cfg since the file no longer exists.
The above documentation should be updated (don’t have a Github account):
xen.cfg no longer exists
Grub’s submenu seems to be on by default (changing GRUB_DISABLE_SUBMENU to true doesn’t seem to change anything)
Messing with Grub seems risky–is there an alternative method for changing the default kernel?
Is there a way to just uninstall kernel-latest? E.g. sudo dnf remove kernel-latest? (Not foolhardy enough to find out myself)
I also had issues with sound cutting off after sometime with the 5.18.x kernels. I’m now using the 5.15 branch and there’s no issue. From what I know, sound issues started with kernel 5.17 and is still not patched.
I’ve had issues with sound cutting off too, although it was always after an absence from the computer. Began after the update, restart returns audio. It hasn’t bothered me greatly.
On the light blue screen that appears immediately after boot, before the grey splash screen, you are given the option to configure how your system boots. Among the choices is one that lets you boot dom0 with an older kernel.
Do you use kernel 5.18 and does a restart make your audio normal?
I use kernel 5.18, at start audio can work, but didn’t have voice after a reboot. Another reboot doesn’t fix the problem.
Has sound after replugging DP line, I don’t know why reboot didn’t work.
I am currently experiencing the EXACT same problem described by @fiftyfourthparallel on my Dell Latitude 5420 machine. Sound works 20% of the times, totally randomly. I switched to kernel-latest for both Dom0 and for the Qubes. This didn’t fix the problem. I am using the latest up-to-date Qubes OS.
