Hi there, i upgraded to the new media-video/pipewire-1.4.1 yesturday and since then, VirtualBox is no longer usable. As soon anything plays any sound, it just instantly crashes. Sadly i do not get any feedback/logs from Virtualbox oder dmesg on why this happens, so for now i can not deliver any useful logging, but downgrading pipewire solves the issue, so it is the upgrade. I can workaround this by disabling Audio in VirtualBox which is sadly no option as i need sound in the VM for my work (Meetings and such) Reproducible: Always Steps to Reproduce: 1. Upgrade to pipewire-1.4 2. Start an VM that has sound enabled 3. Wait until the VM tries to play sound (usually when logging in on Windows) Actual Results: The VM just disappears (it looks like segfault, but i have not logs to backup that claim) Expected Results: Should play sound Portage 3.0.67 (python 3.12.9-final-0, default/linux/amd64/23.0/desktop/plasma, gcc-14, glibc-2.41-r1, 6.13.7-Vamp898 x86_64)

In the effort to get any logs, i upgraded Pipewire again (i still have some time left until i depend on the VM) and tried starting it with VirtualBoxVM --startvm from the command line in hope, to get something out of there. To my surprise, it works starting that way. So i started it again via the GUI using the command VirtualBox And it works there too suddenly... I can no longer reproduce it, sound works fine in VirtualBox after downgrading pipewire and upgrading it again (aka rebuild). Maybe something went wrong at built time? Not sure, but it works flawless now after the rebuild of pipewire.
I am sorry but after an reboot, the issue is back. But at least i can tell you know what VirtualBox says when starting the VM on the commandline It says "Killed" as soon something tries to play sound, nothing more.
What version do you use? Please run `emerge --info app-emulation/virtualbox` and paste the last few lines, it should look something like this: ================================================================= Package Settings ================================================================= app-emulation/virtualbox-7.1.6a::gentoo was built with the following: USE="alsa doc dtrace gui java lvm nls opengl pam pulseaudio sdk sdl udev vboxwebsrv vde vmmraw vnc -dbus -debug (-pch) -python -test" ABI_X86="(64)" PYTHON_SINGLE_TARGET="-python3_10 -python3_11" FEATURES="assume-digests binpkg-docompress binpkg-dostrip binpkg-logs buildpkg-live ccache config-protect-if-modified distlocks ebuild-locks fixlafiles ipc-sandbox merge-sync merge-wait multilib-strict network-sandbox news parallel-fetch pid-sandbox pkgdir-index-trusted preserve-libs protect-owned qa-unresolved-soname-deps sandbox splitdebug strict strict-keepdir unknown-features-warn unmerge-logs unmerge-orphans userfetch userpriv usersandbox usersync warn-on-large-env xattr"

I am sorry for posting the whole emerge --info again, i pressed return to fast and there is no edit feature here. But i tested a different soundcard i could get my hands on, two different soundcards, as i read it could be related to the soundcard. But sadly, it doesn't matter which soundcard i use, the result is the same. I hear the login sound from the Guest OS, i can see in qpwgraph the connection for a split second and then the VM is just gone. So at least this issue seems not to be related with the used Soundcard.
I tried with media-video/pipewire-1.4.1 compiled with -O3 and it works fine for me, I can watch a movie with sound in the vm. I didn't reboot, maybe that was a factor. I'll try again in the next few days.
After the current upgrade to VirtualBox 7.1.8 and pipewire 1.4.2, the situation did not change, sadly. It still instantly crashes as soon the login sound plays. Booting the VM without soundcard works fine.
Sorry for the double post, but i found another workaround. Switching the Audio Device in VirtualBox from "Default" (Whatever that means, probably ALSA), to Pipewire workarounds the issue. I have working sound when setting the VMs soundcard to Pipewire, without crashes.
Pipewire? I do not have pipewire in that list, I tried with default, alsa and pulseaudio, worked with all of them. But it's good there is a workaround.
That's weird indeed.. I don't see any pipewire in the enum at https://github.com/mirror/vbox/blob/master/src/VBox/Main/xml/Settings.cpp#L8272 but maybe that mirror is outdated.
I am so sorry, you're right. Because i use Pipewire as an Pulseaudio replacement, it got mixed in my head. It is Pipewire in the end, but the setting in Virtualbox is called "Pulseaudio". So i am setting to Pulseaudio and then Sound is working fine. I set it to ALSA again to re-check with ALSA and it crashes again, as soon it plays sound. So default seems to mean ALSA. This is what the log says before it crashes ---8<--- 00:00:07.738649 Audio Mixer: Setting sink 'HDA Mixer/Line In' -- channel volumes: ff ff ff ff ff ff ff ff ff ff ff ff 00:00:07.738822 Audio Mixer: Setting sink 'HDA Mixer/Line In' -- channel volumes: ff ff ff ff ff ff ff ff ff ff ff ff 00:00:07.739083 Audio Mixer: Setting sink 'HDA Mixer/Line In' -- channel volumes: ff ff ff ff ff ff ff ff ff ff ff ff 00:00:07.739228 Audio Mixer: Setting sink 'HDA Mixer/Line In' -- channel volumes: ff ff ff ff ff ff ff ff ff ff ff ff 00:00:07.739811 Audio Mixer: Setting sink 'HDA Mixer/PCM Output' -- channel volumes: fd fd fd fd fd fd fd fd fd fd fd fd 00:00:07.739957 Audio Mixer: Setting sink 'HDA Mixer/PCM Output' -- channel volumes: fd fd fd fd fd fd fd fd fd fd fd fd 00:00:07.740939 Audio Mixer: Setting sink 'HDA Mixer/PCM Output' -- channel volumes: fd fd fd fd fd fd fd fd fd fd fd fd 00:00:07.741073 Audio Mixer: Setting sink 'HDA Mixer/PCM Output' -- channel volumes: fd fd fd fd fd fd fd fd fd fd fd fd 00:00:08.388819 ALSA: Using output device "default" ---8<--- Thats the last log entry, after that, the VM is just gone with an Segmentation Fault When started with Pulseaudio, it just continues after that part as normal ---8<--- 00:00:08.392140 Audio Mixer: Setting sink 'HDA Mixer/Line In' -- channel volumes: ff ff ff ff ff ff ff ff ff ff ff ff 00:00:08.392313 Audio Mixer: Setting sink 'HDA Mixer/Line In' -- channel volumes: ff ff ff ff ff ff ff ff ff ff ff ff 00:00:08.392626 Audio Mixer: Setting sink 'HDA Mixer/Line In' -- channel volumes: ff ff ff ff ff ff ff ff ff ff ff ff 00:00:08.392745 Audio Mixer: Setting sink 'HDA Mixer/Line In' -- channel volumes: ff ff ff ff ff ff ff ff ff ff ff ff 00:00:08.393308 Audio Mixer: Setting sink 'HDA Mixer/PCM Output' -- channel volumes: fd fd fd fd fd fd fd fd fd fd fd fd 00:00:08.393457 Audio Mixer: Setting sink 'HDA Mixer/PCM Output' -- channel volumes: fd fd fd fd fd fd fd fd fd fd fd fd 00:00:08.394127 Audio Mixer: Setting sink 'HDA Mixer/PCM Output' -- channel volumes: fd fd fd fd fd fd fd fd fd fd fd fd 00:00:08.394236 Audio Mixer: Setting sink 'HDA Mixer/PCM Output' -- channel volumes: fd fd fd fd fd fd fd fd fd fd fd fd 00:00:10.358356 VMMDev: Guest Additions capability report: (0x4 -> 0x0) seamless: no, hostWindowMapping: no, graphics: no 00:00:10.358808 VMMDev: Guest Additions capability report: (0x0 -> 0x4) seamless: no, hostWindowMapping: no, graphics: yes 00:00:12.574397 VMMDev: Guest Additions capability report: (0x4 -> 0x0) seamless: no, hostWindowMapping: no, graphics: no 00:00:12.575035 VMMDev: Guest Additions capability report: (0x0 -> 0x4) seamless: no, hostWindowMapping: no, graphics: yes 00:00:12.721748 VMMDev: Guest Log: VBOXNP: DLL loaded. 00:00:14.779482 VMMDev: Guest Additions capability report: (0x4 -> 0x0) seamless: no, hostWindowMapping: no, graphics: no 00:00:14.779866 VMMDev: Guest Additions capability report: (0x0 -> 0x4) seamless: no, hostWindowMapping: no, graphics: yes 00:00:16.986377 VMMDev: Guest Additions capability report: (0x4 -> 0x0) seamless: no, hostWindowMapping: no, graphics: no 00:00:16.986708 VMMDev: Guest Additions capability report: (0x0 -> 0x4) seamless: no, hostWindowMapping: no, graphics: yes [...] (And so on) ---8<---
I added an entry to the wiki. Feel free to add more details if you want. I'll close the bug as wontfix, but we have a workaround. Thank you!
