I've only been puzzled by a few oddities: Although the mic is mono, I get a stereo input with 2 controls, which did even influence the sound on both channels separatly, but in a not-so-clear way. Since neither the windows, nor the OSX usb-audio driver are able to fully control the device, especially the internal gain-control, Samson has published a modified driver & tool to control such parameters. I have investigated that tool with an usb-traffic sniffer (usbsnoop). I did also do some experiments with the alsa driver to see, what the controls really do and how the device might be designed internally. I have found out about everything needed to make the device fully supported, I just don't really know how to implement it, so I'm hoping someone will guide and help me. Although I'd really like to, I'm not a kernel hacker. What I basically want to do is remap and rename the mixer-controls and output lines alsa exposes. Is that what the quirks are for? Details about the device and my findings follow below: ====================================================================== ---------------------------------------------------------------------- tiwai - 01-04-06 17:23 ---------------------------------------------------------------------- I recommend you to post this to alsa-devel ML rather than here on BTS in cases of not real "bugs"...
