According to the log of #18, looks like after resuming, the pulseaudio tried to set the pcm to 5.1 channels on the hdmi-surround-extra1, but failed:
D: [pulseaudio] alsa-util.c: snd_pcm_hw_params_set_channels(6) failed: Invalid argument D: [pulseaudio] alsa-util.c: Trying hdmi:2,1 without SND_PCM_NO_AUTO_FORMAT ... D: [pulseaudio] alsa-util.c: Managed to open hdmi:2,1 I: [pulseaudio] alsa-util.c: Trying to disable ALSA period wakeups, using timers only D: [pulseaudio] alsa-util.c: snd_pcm_hw_params_set_channels(6) failed: Invalid argument D: [pulseaudio] alsa-util.c: Trying plug:hdmi:2,1 with SND_PCM_NO_AUTO_FORMAT ... could you upload the output of 'cat /proc/asound/$(nvhdmi sound card)/eld*' before and after suspend/resume. And could you redo the test of #12 and find if there is the error of "snd_pcm_hw_params_set_channels(6) failed" in it? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1888598 Title: pulseaudio has is buggy with hdmi audio and sleep/wake To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/1888598/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
