Last week I've updated my hardware and after installing Ubuntu 12.04 I has some problems with the sound, there was:
1) I replaced the old mainboard with a Asus P8H77-M Pro board with onboard sound and found out that I didn't have any sound controls: system settings -> Sound did not respond. Answers to this problem were: go to the sounds settings. This doesn't work when sounds controls aren't willing to open. (would like a sollution for this)
I uninstalled PulseAudio and rebooted. Through the gnome alsamixer I could set the master output and sound is working now, although not as I would like it to work. Audio control now opens but no devices/settings can be found.
2) My second problem is the USB sound device not showing up. I've used this USB headset on my old system so I know this should be working. What are the things that I can check to figure out what the problem is? Alsa mixer is showing an USB device and output is set to max but still no sound. Pulse did recognise it was a logitech but I had no sound there as well (se first problem).
I'm a novice user.
Thanks in advance.
