This is possibly a duplication of Bug #548707 but it doesn't seem as extreme.
I've unlocked the PCM volume control and used alsamixer to lower the volume. I've set it to 70% and the logon read sound doesn't appear to distort. Haven't rebooted yet to see if setting stays. -- Distorted sound when master volume set to 65% or higher https://bugs.launchpad.net/bugs/571699 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
