Comment 2 for bug 559939

I also got the same device (http://www.dizeg.net/digit/photo/caplior7/rimg1555.jpg) ... and with it the same symptoms. Using alsamixer, going from 63.00 dB (max) gain volume down to 11.00dB only slightly changes the volume (it's still very loud at this point). Going one step down to 10.99dB completely mutes the output. Besides from that, it works fine. Activating "Analog Mono Input" in PulseAudio volume control (Hardware tab, "Profile"-setting) adds a digital noise the audio output, but from the VU-meter, input seems to work.

I just noticed: When setting the profile to "Digital Stereo Duplex (IEC958)" (didn't see this profile last time I checked), volume control seems to work. But lowering the volume adds noise to the output sound ... might be the poor audio processor. Can anybody confirm this?
