Hi there.

I would like to get a confirmation on below.

One of my USB soundcards is a M-Audio Transit.

cat /proc/asound/card0/stream0

lists below:

M-Audio Transit USB at usb-0000:00:1d.2-1.3, full speed : USB Audio

Playback: Status: Running Interface = 1 Altset = 3 URBs = 2 [ 1 1 ] Packet Size = 196 Momentary freq = 44100 Hz (0x2c.199a) Interface 1 Altset 1 Format: 0x20 (24 bits) Channels: 2 Endpoint: 3 OUT (ADAPTIVE) Rates: 48001 - 96000 (continuous) Interface 1 Altset 2 Format: 0x20 (24 bits) Channels: 2 Endpoint: 3 OUT (NONE) Rates: 8000 - 48000 (continuous) Interface 1 Altset 3 Format: 0x2 (16 bits) Channels: 2 Endpoint: 3 OUT (ASYNC) Rates: 8000 - 48000 (continuous)

Do I interprete it right that the Transit runs in asynchronous USB mode up to 48khz and 16bit? Does above also mean that <48/24 is not supported?
