I have the same problem with what looks like a very similar chip, I would guess it's probably related:
Intel Corporation N10/ICH 7 Family High Definition Audio Controller (rev 02) Conexant CX20551 (Waikiki) Basically I get distortion on all volumes because PCM is always set to around 100% by ALSA. I had this problem in Karmic as well. I fixed it with a config tweak that I read on a Wiki somewhere, I can't find it at the moment otherwise I would share it here. -- PCM 100% is much higher than 0 dB https://bugs.launchpad.net/bugs/541802 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
