** Description changed:
Problems with the sound (chipset z97). I've got the sound in Windows -
so it is a software bug. Freshly installed default system. First time
this was Kubuntu 14.04 then it was upgraded to 14.10 for a fresh kernel.
No effect to the problem. Found the similar problem
Devices list output and screeshot of alsamixer in attachment:
meklon@meklon-desktop:~/Музыка$ aplay -L
default
Playback/recording through the PulseAudio sound server
null
Discard all samples (playback) or generate zero samples (capture)
pulse
PulseAudio Sound Server
sysdefault:CARD=PCH
Tried this with no effect:
meklon@meklon-desktop:~/Музыка$ amixer set Master 100 unmute
Simple mixer control 'Master',0
Capabilities: pvolume pvolume-joined pswitch pswitch-joined
Logged the pulseaudio log. What should I do now? I can reproduce the bug
on a clean live-dvd image.

I'll try to deattach the video card and test without it. The system will
have only one physical output.
