ALSA: usb-audio: Set 48 kHz rate for Rodecaster

2020-06-15T06:47:05+00:00

Like the Line6 devices, the Rode Rodecaster Pro does not support
UAC2_CS_RANGE and only supports a sample rate of 48 kHz.

Tested against a Rode Rodecaster Pro.

ALSA: usb-audio: Filter out unsupported sample rates on Focusrite devices

2020-04-18T19:08:39+00:00

Many Focusrite devices supports a limited set of sample rates per
altsetting. These includes audio interfaces with ADAT ports:
 - Scarlett 18i6, 18i8 1st gen, 18i20 1st gen;
 - Scarlett 18i8 2nd gen, 18i20 2nd gen;
 - Scarlett 18i8 3rd gen, 18i20 3rd gen;
 - Clarett 2Pre USB, 4Pre USB, 8Pre USB.

Maximum rate is exposed in the last 4 bytes of Format Type descriptor
which has a non-standard bLength = 10.

Merge branch 'topic/usb-uac2-effect-unit' into for-next

2020-02-17T14:30:32+00:00

Merging the UAC2 effect unit parser improvement.  As it's based on the
previous usb-audio driver fix, it was deviated from for-next branch.

ALSA: usb-audio: Add support for Presonus Studio 1810c

2020-02-15T08:46:16+00:00

This patch adds support for Presonus Studio 1810c, a usb interface
that's UAC2 compliant with a few quirks and a few extra hw-specific
controls. I've tested all 3 altsettings and the added switch
controls and they work as expected.

More infos on the card:
https://www.presonus.com/products/Studio-1810c

Note that this work is based on packet inspection with
usbmon. I just wanted to get this card to work for using
it on our open-source radio station:
https://github.com/UoC-Radio

v2 address issues reported by Takashi:
* Properly get/set enum type controls
* Prevent race condition on switch_get/set
* Various control naming changes
* Various coding style fixes

v3 improve readability of sample rate filtering
and some other minor changes.

ALSA: usb-audio: Add clock validity quirk for Denon MC7000/MCX8000

2020-02-13T06:18:58+00:00

It should be safe to ignore clock validity check result if the following
conditions are met:
 - only one single sample rate is supported;
 - the terminal is directly connected to the clock source;
 - the clock type is internal.

This is to deal with some Denon DJ controllers that always reports that
clock is invalid.

ALSA: usb-audio: Apply 48kHz fixed rate playback for Jabra Evolve 65 headset

2020-02-11T11:17:06+00:00

Jabra Evolve 65 headset appears as if supporting lower rates than
48kHz, but it actually doesn't work but with 48kHz for playback.

This patch applies a workaround to enforce the 48kHz like LINE6
devices already did.  The workaround is put in a unified helper
function, set_fixed_rate(), to be called from both places now.

ALSA: usb-audio: Use lower hex numbers for IDs

2020-01-05T08:20:44+00:00

For consistency reason, make all hex numbers with lower alphabets for
USB ID entries.  It improves grep-ability and reduces careless
mistakes.

   Morimoto-san.
