Public bug reported: When using a "Logilink USB2.0 to Audio Adapter" (which apparently uses a Tenx Technology TP6911 chip, judging from USB id 1130:f211) under Lucid Beta, the volume control does not work. Sound is always played at same volume.
The volume slider in panel can be used but doesn't have any effect on volume, except that going down near 0 suddenly mutes the sound. Also, when using the slider in Volume Settings dialog, moving the volume above the 100% mark actually increases playback volume - but I assume this is done by Pulseaudio in software? Aside from the volume issue, the device seems to basically work - it is displayed in Audio Settings as additional input/output device, and it plays sound (didn't test recording, though). According to http://www.tenx.com.tw/product_detail.aspx?ProductID=192 the chip is supposed to have "64-level volume control" - is that not true, or does the driver not make these 64 levels available? This is with up-to-date Lucid Beta, on EeePc 701. The normal built-in sound card works fine, including volume control.
