Aborting. This is a driver error. The sound card claims to have 256 volume levels, but the dB range is from 0 to 0 dB. Most likely the USB device exports invalid volume range data, and ALSA just passes this along. ALSA should not do that, it should simply admit that the dB data it has is invalid and not pass this invalid information on. Please bring this up on alsa-devel and ask them to make a few very basic validity checks for the dB data and ignore it if it fails these tests. I could work around this in PA too. However I believe the right place for a fix for this is ALSA, not PA.
