I expirienced similar problems. https://bugs.gentoo.org/show_bug.cgi?id=506188
pulseaudio hangs when it tryes to access switched off audio device. How I reproduced the problem: I started Gnome 3 session with disabled discrete GPU + HDMI audio. Disabled via vgaswitcheroo before session start. Switched on radeon GPU via vgaswitcheroo. Stopped pulseaudio daemon and launched it as foreground process with -vvv options. Launched sound applet from Gnome Control Center and verified that there is an HDMI Audio output device. Switched off radeon GPU via vgaswitcheroo. Tried to access switched off HDMI Audio by pressing 'Test Speakers' button. The outcome is not responding Sound applet and error messages from pulseaudio: D: [alsa-source-ALC271X Analog] ratelimit.c: 241 events suppressed D: [alsa-source-ALC271X Analog] memblock.c: Pool full W: [alsa-source-ALC271X Analog] asyncq.c: q overrun, queuing locally D: [alsa-source-ALC271X Analog] memblock.c: Pool full W: [alsa-source-ALC271X Analog] asyncq.c: q overrun, queuing locally D: [alsa-source-ALC271X Analog] memblock.c: Pool full W: [alsa-source-ALC271X Analog] asyncq.c: q overrun, queuing locally D: [alsa-source-ALC271X Analog] memblock.c: Pool full W: [alsa-source-ALC271X Analog] asyncq.c: q overrun, queuing locallyt D: [alsa-source-ALC271X Analog] memblock.c: Pool full W: [alsa-source-ALC271X Analog] asyncq.c: q overrun, queuing locally D: [alsa-source-ALC271X Analog] memblock.c: Pool full The pulseaudio process is not reacted to SIGTERM and SIGKILL. ** Bug watch added: Gentoo Bugzilla #506188 https://bugs.gentoo.org/show_bug.cgi?id=506188 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1210470 Title: Switching to integrated card with vgaswitcheroo makes the kernel to hang, until pulseaudio is killed To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/1210470/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
