ALSA: usb-audio: add quirk to fix Hamedal C20 disconnect issue

2022-11-10T06:50:30Z

For Hamedal C20, the current rate is different from the runtime rate, snd_usb_endpoint stop and close endpoint to resetting rate. if snd_usb_endpoint close the endpoint, sometimes usb will disconnect the device.

ALSA: usb-audio: Add DSD support for Accuphase DAC-60

2022-11-09T06:24:30Z

Accuphase DAC-60 option card supports native DSD up to DSD256, but doesn't have support for auto-detection. Explicitly enable DSD support for the correct altsetting.

ALSA: usb-audio: Add quirk entry for M-Audio Micro

2022-11-08T14:07:49Z

M-Audio Micro (0762:201a) defines the descriptor as vendor-specific, while the content seems class-compliant. Just overriding the probe makes the device working.

ALSA: usb-audio: Remove redundant workaround for Roland quirk

2022-11-08T06:59:37Z

The recent fix for the delayed card registration made the current workaround for QUIRK_AUTODETECT superfluous, since the card registration itself is delayed until the last interface probe. This patch drops the redundant workaround in create_autodetect_quirks() for simplification.

ALSA: usb-audio: Yet more regression for for the delayed card registration

2022-11-08T06:59:30Z

Although we tried to fix the regression for the recent changes with the delayed card registration, it doesn't seem covering the all cases; e.g. on Roland EDIROL M-100FX, where the generic quirk for Roland devices is applied, it misses the card registration because the detection of the last interface (apparently for MIDI) fails. This patch is an attempt to recover from those failures by calling the card register also at the error path for the secondary interfaces. The card register condition is also extended to match with the old check in the previous patch, too (i.e. the simple check of the interface number) for catching the probe with errors.

ALSA: usb-audio: Add quirks for M-Audio Fast Track C400/600

2022-10-21T12:29:50Z

M-Audio Fast Track C400 and C600 devices (0763:2030 and 0763:2031, respectively) seem requiring the explicit setup for the implicit feedback mode. This patch adds the quirk entries for those.

ALSA: usb-audio: Use snd_ctl_rename() to rename a control

2022-10-21T06:17:08Z

With the recent addition of hashed controls lookup it's not enough to just update the control name field, the hash entries for the modified control have to be updated too. snd_ctl_rename() takes care of that, so use it instead of directly modifying the control name.

ALSA: usb-audio: Avoid superfluous endpoint setup

2022-10-09T10:43:26Z

After splitting to snd_usb_endpoint_set_params() and *_prepare(), the skip of each function should be checked with different flags, while we still use ep->need_setup as the single one. Introduce ep->need_prepare for indicating the need of prepare, and also add the missing check of ep->need_setup at the set_params.

snd_usb_endpoint_set_params() should return zero for a success, but currently it returns the sample rate. Correct it.

ALSA: usb-audio: Apply mutex around snd_usb_endpoint_set_params()

2022-10-09T10:43:25Z

The protection with chip->mutex was lost after splitting snd_usb_endpoint_set_params() and snd_usb_endpoint_prepare(). Apply the same mutex again to the former function.
