Update: Loged in as guest and all works as charm. Using my account (administrator) nothing works and i am not able to locate advanced user management options :(
First of all - I use USB headset. there were some troubles with recognition at first, but prestigio were listed under hardware, so i activated it and all worked.
Now after I had to unplug headset and restart lappy, there is no sound devices at all listed under hardware tab. I cant adjust volume there. There is sound from built in speakers, but not from headset.
alsamixer shows me both built in audio card and prestigio (headset). I can choose them, but after esc and leaving alsa it rolls back to "default"
Following this thread, There are no Audio devices listed under hardware tab of audio preferences as a result no sound I gathered this info
Audio device: Intel Corporation 82801H (ICH8 Family) HD Audio Controller (rev 03) Subsystem: Acer Incorporated [ALI] Device 011e Flags: bus master, fast devsel, latency 0, IRQ 47 Memory at 98400000 (64-bit, non-prefetchable) [size=16K] Capabilities: <access denied> Kernel driver in use: HDA Intel Kernel modules: snd-hda-intel
but solution offered (try killall pulseaudio; rm -r ~/.pulse* from terminal and logout or reboot) gave this result
pulseaudio: no process found rm: remove write-protected regular file `/xxxxxx/.pulse/a336866c5ace61b2c9bc648a0000004f-runtime'? rm: cannot remove `/xxxxxxx/.pulse': Directory not empty
I am at lost now. Multiple restarts with headset on and off have not yielded any other results. Any suggestions? this is my first time using ubuntu and i am at best confident user in windows, so my own knowledge is quite lacking on issue...
update: aplay -l gives this as result.
