Public bug reported:
Ubuntu 16.04 on 64 bit produces hissing sound (just by my - far from
being 'musical' - ear, it sounds like a sinus wave with frequency about
1KHz or so) on headphones. Interestingly, after boot this does not
happen and usually can be hear only after the first application which
makes any sound (but not always, sometimes it starts later). But if any
time it starts, it remains, whatever I do, exiting the application
(which makes the sound) even by killing pulseaudio process, etc. I've
read a lot on this issue but usually - it seems - always notebook
problems mentioned, however it's a desktop machine (Asrock FM2A88M
extreme4+ motherboard, AMD A6-6400K CPU, integrated audio). It seems it
uses snd_hda_intel kernel module though. I've tried advices mentioned by
various resources throughout the net, disabling powersave problems,
using hdajackretask from alsa-tools-gui, etc, but they didn't help.
