Losing audio on the host when VirtualBox is installed

zimbatm commented 8 years ago

Issue description

When I enable virtualisation.virtualbox.host.enable = true; I reliably lose the sound on next reboot. Switching to the previous generation restores the sound again.

I think it might be due to the udev triggers that are being installed but I don't really know. Looking for some clues on how to dig this further.

~~Does it work if you plug in headphones?~~ EDIT: nevermind, I had a different issue whereby only headphones would work.

Loading snd_hda_codec_realtek and restarting my session restores the audio

zimbatm commented 8 years ago

So I can add this to the boot.kernelModules array and it should fix the problem (and the dell_led). I think the issue is the /etc/modules-load.d/nixos.conf load order:

kvm-intel
vboxdrv
vboxnetadp
vboxnetflt
ipv6
cpufreq_ondemand
loop
atkbd
ppp_mppe
nf_conntrack_ftp
tun
snd_pcm_oss

yawnt commented 8 years ago

so basically if i understand correctly we should enable a specific ordering in here https://github.com/NixOS/nixpkgs/blob/master/nixos/modules/virtualisation/virtualbox-host.nix#L53 ?

zimbatm commented 8 years ago

I changed the order with the following change but it doesn't fix the problem for me. It must be something else.

Well I ran out of ideas again. 4.5 and 4.6 also have the same issue, 4.6 even has two backtraces instead of one.

Can you maybe give me your lsmod and computer model to see if there are any commonalities ?

yawnt commented 8 years ago

http://sprunge.us/DEWK

here is my lsmod, although this is with virtualbox disabled (i needed my sound :( ), will you be needing one with virtualbox on? ThinkPad T460s

sprunge.us is pretty cool, didn't know it...

I've got virtualbox disabled too

zimbatm commented 8 years ago

Interesting, we all have the snd_hda_codec_realtek module

EDIT: The X1 below doesn't have the realtek codec

zimbatm commented 8 years ago

Mind pasting the lspci output as well ?

lsmod without virtualbox is good enough

dvc94ch commented 8 years ago

Nice! What's the saying? Great minds think alike =P On the other hand there aren't too many alternatives with recent hardware that I'm aware of, so I guess it's not uncommon for linux users to have a xps...

another datapoint: my laptop is using snd_hda_codec_idt and has virtualbox host enabled, but audio isnt broken

DamienCassou commented 8 years ago

I have the same issue with linux 4.7. I'm on Lenovo T460s as well.

DamienCassou commented 8 years ago

I'm not sure it's related, but the laptop reboot takes more than 2 minutes when VBox is enabled and less than 30 seconds when disabled.

DamienCassou commented 8 years ago

I consider this problem a major bug as I (and certainly other) spend their working time in a VM and communicating with remotes colleagues.

FRidh commented 8 years ago

Perhaps updating ALSA helps? http://www.alsa-project.org/main/index.php/Changes_v1.1.1_v1.1.2 We're on 1.1.1 now.

zimbatm commented 8 years ago

Reported the issue upstream: https://www.virtualbox.org/ticket/15919

The next thing to do would be to upgrade VirtualBox as we're a couple of releases behind (and probably won't get support from upstream because of that).

@FRidh: I think the issue is on the kernel level. If the audio driver isn't loaded I don't think it will make a difference what audio library we're using.

domenkozar commented 8 years ago

Looks similar to https://www.virtualbox.org/ticket/15859 except that we don't have those versions.

domenkozar commented 8 years ago

Seems to be happening on 5.1.4, we should try upgrading to 5.1.2.

https://www.virtualbox.org/ticket/15806

DamienCassou commented 8 years ago

I'm trying to build 5.1.2, but currently fails: https://github.com/NixOS/nixpkgs/pull/17502

DamienCassou commented 8 years ago

The sound problem is still there with 5.1.2 :-(.

aszlig commented 8 years ago

Haven't read all the comments, but could you try it with pulseSupport = true?

DamienCassou commented 8 years ago

@aszlig I've tried to activate pulseSupport everywhere, but this doesn't fix the problem with VirtualBox 5.1.4.

DamienCassou commented 8 years ago

@aszlig I merged all the changes (to get 5.1.6) you merged yesterday and I still have the issue: my host computer takes 2 minutes more to boot and I don't have sound on the host.

DamienCassou commented 8 years ago

@zimbatm @dvc94ch @yawnt Do you guys have workarounds?

DamienCassou commented 8 years ago

I found a workaround for me:

sudo modprobe snd_hda_intel

Just doing that is enough, no need to restart the session. The boot is still way too long though (more than 2 minutes whereas it's less than 30 seconds without VirtualBox installed).

yawnt commented 8 years ago

@DamienCassou that modprobe does not work for me :(

DamienCassou commented 8 years ago

@yawnt try replacing snd_hda_intel by snd_hda_codec_realtek. Also try logging out and back in.

aszlig commented 8 years ago

@DamienCassou: I'm assuming you mean the host, what do go get with systemd-analyze blame?

DamienCassou commented 8 years ago

@aszlig I'm only talking about the host, right.

Let me know what other data I can provide.

domenkozar commented 8 years ago

@lapp0 can you pastebin journalctl -b and journalctl -k for the time when audio fails?

lapp0 commented 8 years ago

@domenkozar

journalctl -b for my last boot (I have audio until I reboot) http://pastebin.com/raw/rayr66u7 journalctl -k http://pastebin.com/raw/8j2QcJgh

domenkozar commented 8 years ago

@lapp0 can you also paste $ lspci -nn?

Also, does the workaround help for you: sudo modprobe snd_hda_intel?

That doesn't do it since amixer doesn't work

domenkozar commented 8 years ago

Although sound is indeed important, I'll let this go as a blocker. Hopefully we can fix it after the release asap.

DamienCassou commented 8 years ago

I have the impression this is fixed in channels/16.09.
