Re: [qubes-users] No sound in XPS9310

2021-10-13 Thread Fabrizio Romano Genovese
After a bit of time I had the opportunity to investigate this a bit 
further. Even running speaker-test on sys-audio results in the audio 
stammering, and sys-audio manages the device directly... Could this be a 
problem between fedora33 and my sound card? What can I do to pinpoint the 
problem?

Any help is appreciated!

Re: [qubes-users] No sound in XPS9310

2021-09-16 Thread Fabrizio Romano Genovese
Hello all,

I managed to finally install Qubes 4.1, but the audio problem is still not 
fixed. As awokd pointed out, in Qubes 4.1 I can define an audio-vm which, 
having fedora33, correctly recognizes my audio card. 

I first tried the easy way: I created a sys-audio vm, and assigned the 
audio card to it. Unfortunately, the audio doesn't really work smoothly: 
Playing youtube videos on sys-audio is very slow and the sound is 
continuously cackling.

Investigating things further, it seems that there is already some salt 
script I can use to create sys-audio. So I removed my sys-audio vm and I 
tried with 
sudo qubesctl state.sls qvm.sys-audio
that lists two processes, one succeds and the other one fails. After this I 
have sys-audio again, but it is not used by default by any other vm. I 
tested with 
qvm-prefs untrusted audiovm sysaudio 
but audio still does not work. Youtube videos now do not really start. If I 
set audio back to dom0 and reboot the vm instead they do (but obviously I 
cannot hear anything given that dom0 has fedora32 which doesn't like my 
card).

I feel like there's something very simple that I am missing. Am I maybe 
issuing the wrong salt command to set up sys-audio?

Cheers,
Fab

Alas, no, I really have the AX500. The AX1650 is waay much more well 
behaved and it is the one that is usually shipped on XPS developer edition. 
Unfortunately XPS developer edition does not have a 32GB RAM option, which

The sad thing is that audio worked perfectly on kernel 5.4... I'll try to

fedora 33 5.10 kernel supports much more devices and audio works in the
upstream fedora on both the 9700 and 9310 dells.  I'll see if I can get a
patch into qubes the upstream kernel modules which fedora has added or at

Thanks for jumping in, Rama. It's difficult to troubleshoot hardware

Re: [qubes-users] No sound in XPS9310

2021-02-08 Thread Rama McIntosh
I think your dell has different wifi and I think audio.   The wifi driver
for the xps 9310 is iwlwifi.   Here is some firmware info:
https://support.killernetworking.com/knowledge-base/killer-ax1650-in-debian-ubuntu-16-04/
and here is some qubes specific info on your wifi driver:
https://github.com/QubesOS/qubes-issues/issues/5615

I think the audio is different too, as the xps 9700 needs the 5.10 kernel
to work, but the base-config patch above does enable
CONFIG_SND_SOC_SOF_INTEL_SOUNDWIRE which I think you need too.

To patch the kernel you must build it from source with qubes-builder
https://www.qubes-os.org/doc/qubes-builder/.   First configure it.  Then
change kernel to master branch in builer.conf.after the "make

Fabrizio Romano Genovese:


I installed qubes on a Dell XPS9310. I was using kernel 5.4.90 and sound
was working, but wi-fi did not. So I upgraded to kernel 5.10.13 and now I
have both wifi and sound not working :D

It seems that the sound issues are due to a problem with driver
sof-audio-pci.
In this thread: https://groups.google.com/g/qubes-users/c/Fa65-e8vqdM it
turns out another user was having a similar problem with a dell 9700, which
was apparently solved. Indeed in the thread it is said:

Audio works (with kernel 5.10 and attached kernel base-config patch  +
latest 1.6.1 sof-bin firmware https://github.com/thesofproject/sof-bin and
alsa-ucm-config files.   see
https://blog.fts.scot/2020/07/04/dell-xps-2020-how-to-get-audio-working-on-linux/
for alsa ucm config ).

Unfortunately, I am not technically skilled enough to really understand the
fix. Does it mean that I have to download kernel 5.10 (from were?), apply
the patch provided in the thread (how?), include firmware and config files
(how?) and then compile and install?
As you can see I don't really have a specific question, and I'm more in
search of a few clarifications to understand how to apply an apparently
already available solution. :)


Per https://groups.google.com/g/qubes-users/c/Fa65-e8vqdM, are you 
running Qubes 4.1? That might be the first place to start. It implements 
audio in a separate VM, which might automagically resolve the issue or 
at least make for a more easily implemented solution. In that case, 
you'll want your VM's kernel to be the latest, so in dom0 do sudo 
qubes-dom0-update kernel-qubes-vm-latest (from memory). See if the audio 
driver loads in the audio VM. If not, it gets more complex.


You could convert it to an HVM which would allow you to recompile the 
kernel internal to the VM using standard Linux procedures- check 
documentation for the distribution you're using. If you didn't want to 
convert to HVM, I think you would have to build a kernel for dom0 first 
per 
https://www.mail-archive.com/qubes-users@googlegroups.com/msg10886.html, 
then package for VM usage with 
https://www.qubes-os.org/doc/managing-vm-kernel/#installing-different-vm-kernel-based-on-dom0-kernel 
(note I haven't attempted this before).
