I am also facing the same problem my speakers give much better sound with Windows compared to Ubuntu 12.10. If i try to amplify the volume in sound settings, sound is not clear. It would be good to get this fixed.
I didn't face any problem with Fedora also. Using Ubuntu first time and will be good to get it fixed. I am not sure if the below bug may solve this problem. I tried it but doesnt work. https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/876020 -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to alsa-driver in Ubuntu. https://bugs.launchpad.net/bugs/938064 Title: [7650E6G, Conexant CX20549 (Venice), Speaker, Internal] volume slider problem (bad slider range) Status in “alsa-driver” package in Ubuntu: Confirmed Bug description: Check screenshots with alsamixer opened: Maximal slider value is ok (internal speakers are loud): http://img7.imageshack.us/img7/1998/volumemax.png But at (approximately) 70% and lower slider values, speakers are absolutely quiet: http://img18.imageshack.us/img18/1833/volumemin.png So I have all speakers effective volume range only on 30% range of slider.
