Public bug reported:
good day all
this is my first bug report, please be nice
I have had this problem with Linux Mint 14 , Linux Mint 15 and now with
Ubuntu Gnome 15.04, Ubuntu Gnome 15.10 again.
May I add, I recently got my USB headset while using Ubuntu 15.04 so the
USB headset is not the problem
COLD BOOT
What happens: on cold boot, headphones and speakers occasionally work,
USB headphones always work when plugged in or when hotplugged. Trying to
unmute, adjust sound volume etc on headphones or speakers is pointless,
nothing seems to make a sound
In sound adapters, all adapters are listed, adapter switches between
speakers and headphones as expect, inshort sound adapter/s work exactly
as expected/required BUT just no sound.
RESUME
When I resume from sleep, sound magically works (headphones and
speakers) (and USB works like normal), I am not sure what other
information is required, but I gave what I thought is relevant.
lspci -v | grep Audio
