Subject: [PATCH AUTOSEL 5.5 63/75] ALSA: usb-audio: Add Pioneer DJ DJM-250MK2 quirk
From: František Kučera <franta-linux@...ntovo.cz>
[ Upstream commit 73d8c94084341e2895169a0462dbc18167f01683 ]
Pioneer DJ DJM-250MK2 is a mixer that acts like a USB sound card.
The MIDI controller part is standard but the PCM part is "vendor specific".
Output is enabled by this quirk: 8 channels, 48 000 Hz, S24_3LE.
Input is not working.
