Greetings, I am fairly new to USB dev (in linux in particular, but also in general), but I would very much like to try to get support for the above device working in snd-usb-audio. - Is this an appropriate place to discuss snd-usb-audio? - Are there any recommended reading pointers for behavior of the quirk table? I patched parse_audio_format_rates_v2(), get_sample_rate_v2(), and set_sample_rate_v2(), and through some sort of beginner luck was able to get aplay audio out of the first two channels. That was incomplete hackery though (eg fixed sample rate), and I would like to learn how to properly add quirk support. There have been other reports that this device worked OOTB, but I fail to see how! I've also been examining the traffic to the device with wireshark and a win7 vm, but the learning curve for USB is a bit steep, so I am digesting. (: If anyone can provide suggestions on lsusb output alone, here's what I have: http://pastebin.com/pA9MLQet cheers, Greg [x-post from alsa-devel due to empty thread - see: http://mailman.alsa-project.org/pipermail/alsa-devel/2015-July/094682.html]
