-Subject: ALSA: usb-audio: Add quirk for Microsoft Modern Wireless Headset
-
-From: Takashi Iwai <tiwai@suse.de>
-
-[ Upstream commit 3da435063777f8d861ba5a165344e3f75f839357 ]
-
-Microsoft Modern Wireless Headset (appearing on the host as "Microsoft
-USB Link") has a playback and a capture mixer volume/switch, but they
-are fairly broken. The descriptor reports wrong dB ranges for
-playback, and the capture volume/switch don't influence on the actual
-recording at all. Moreover, there seem instabilities in the
-connection, and at best, we should disable the runtime PM.
-
-So this ended up with a quirk entry for:
-- Correct the playback dB range;
- I picked up some reasonable values but it's a guess work
-- Disable the capture mixer;
- it's completely useless and confuses PA/PW
-- Suppress get-sample-rate, apply the delay for message handling,
- and suppress the auto-suspend
-
-The behavior of the wheel control on the headset is somehow flaky,
-too, but it's an issue of HID.
