This is still an error in 10.04 , and also in Ubuntu Studio 10.04. I get the message when I attach my USB A/D D/A device from Behringer, which has lineout level audio out:

In this case, a volume range from 0 dB to 0 dB _does_ make sense. It's line level output. The kernel driver should understand such devices if Ubuntu Studio wants to be treated seriously as a digital audio workstation. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/333565 Title: pulseaudio reports several errors from alsa-utils after upgrade to 9.04 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
