Looks like this bug: https://bugs.freedesktop.org/show_bug.cgi?id=110916#c5 > Are there any suggestions I could try to get this to work correctly after > suspend/resume events? Workaround suggested at the link above: add "snd_hda_intel.probe_mask=0x01" to your kernel parameters at boot. This kernel parameter renders any hdmi audio output you might have unavailable and therefore unusable, though. Good luck. > Thanks in advance, > > John > -- “We are all in the gutter, but some of us are looking at the stars.” ― Oscar Wilde, Lady Windermere's Fan
