[arch-general] No working sound with systemd and pulseaudio ?
Hello. Yesterday, I wanted to test systemd, and all worked well, thanks to the wiki. For this test, I used a VirtualBox machine with archlinux in it. I didn't want to bust my main computer. There is big problem. Audio is not working. Every single time sound is needed, I got something like this in my /var/log/errors.log [pulseaudio] bluetooth-util.c: org.bluez.Manager.ListAdapters() failed: org.freedesktop.systemd1.LoadFailed: Unit dbus-org.bluez.service failed to load: No such file or directory. See system logs and 'systemctl status dbus-org.bluez.service' for details. It is blocking every sound, even if soundcard is well detected. Packages lists : PulseAudio 2.1-1 systemd 188-2 systemd-arch-units 20120704 systemd-sysvcompat 188-2 I have the same kind of logs with my main computer, with classical initscripts, but at least, sound is working. [pulseaudio] bluetooth-util.c: org.bluez.Manager.ListAdapters() failed: org.freedesktop.DBus.Error.Spawn.ChildExited: Launch helper exited with unknown return code 1 Any idea ? Thanks ! -- Frederic Bezies fredbezies@gmail.com
Have you unmuted the channels?

All channels are activated. I will try systemctl start alsa-restore and see... But that's weird :( -- Frederic Bezies fredbezies@gmail.com
Have you unmuted the sound card's own channels too? And not just the pulseaudio's.

Both pulseaudio and sound cards channels are unmuted. -- Frederic Bezies fredbezies@gmail.com

Stinks like a virtualbox bug. Alsamixer shows me that all channels (both pulseaudio and sound card ones) are opened and 100% volume. And when I enter, either in virtualbox or in my real computer amixer to see if there is any difference, I get twice : $ amixer scontrols Simple mixer control 'Master',0 Simple mixer control 'Capture',0 Will test with qemu and see if it is a bug in virtualbox or not. -- Frederic Bezies fredbezies@gmail.com

It is a virtualbox bug. Verified in qemu, and sound it working, even if qemu is very slow with gnome shell. -- Frederic Bezies fredbezies@gmail.com
It is a virtualbox bug.
It probably is but that is no certainty. Virtualbox is or was atleast a good example of how a user loved and useful software can still be far from good and safe code correctness. The project leader of OpenBSD had a bug report and eventually found it was virtualbox's fault, commenting "We don't know how other operating system products continue running when the userland ecx register gets clobbered on a return from a page fault, but at least people should be aware that there is likely some security risk from running that product." https://forums.virtualbox.org/viewtopic.php?p=17930 Note this comment which ignores the underlying issues. "One one hand, the documentation for VBox clearly shows FreeBSD as the only supported BSD, and only having "limited support". Outside of the supported guest OS's is strictly "your mileage may vary" territory, and people should be more clearly indicating they are using virtualization when submitting bug reports. On the other hand, Theo needs to stop worrying so much. Virtualization isn't going away, and it's a trend that needs to be adopted and accounted for, not whined about. It's a golden opportunity to attract users who may have not wanted to make the hardware investment to throw BSD on a dedicated rig but now can try it out with no commitment. OMG VIRTUALIZATION IS SCARY isn't the right way to approach it." The original thread can be seen here, if you wonder if there is any other basis for that comment. http://webcache.googleusercontent.com/search?q=cache:Gwz0lBB1_NgJ:old.nabble.com/Bug-reports-regarding-Innotek-VirtualBox-td15907184.html+&cd=1&hl=en&ct=clnk&gl=uk -- _______________________________________________________________________ 'Write programs that do one thing and do it well.
