[alsa-devel] [PATCH] ALSA: usb: Add support for Zoom R16/24 capture and midi interfaces
This makes the midi interface and capture work out of the box with R16 (and presumably R24 too but untested). Playback stream would also seem to function fine except for one caveat: no sound is produced, so it is disabled for now.

Could you give more comments in the playback iface why it's disabled? Ditto for ifnum=0.
thanks,
Takashi

Sure, I'll post an updated patch with added comments.
In the meanwhile I started looking at the mixer - this is just guessing but maybe its starting with outputs muted which could explain the playback stream running but without sound.
The descriptors for interface 0 are garbage but what is there would seem to map to logical elements by subtype and terminaltype, after those the data doesn't seem to add up (eg number of input/output channels missing/wrongly placed etc):
** UNRECOGNIZED: 0b 24 01 00 01 35 00 03 01 02 03 -> Header? ** UNRECOGNIZED: 0c 24 02 05 01 01 00 02 03 00 00 00 -> USB streaming input terminal? ** UNRECOGNIZED: 09 24 03 08 01 03 00 05 00 -> Speaker output terminal? ** UNRECOGNIZED: 0c 24 02 09 01 02 00 08 00 00 00 00 -> Microphone input terminal? ** UNRECOGNIZED: 09 24 03 0c 01 01 00 09 00 -> USB streaming output terminal?
Anything there that might ring a bell, or other ideas where to start poking at this thing?
FWIW there are other unrecognized descriptors too but those are associated with the other interfaces, which I guess I can ignore for now...

Yeah, most of these look almost sane, so any off-by-one firmware issue?
