ALSA: usb-audio: Apply rate limit to warning messages in URB complete callback

2018-08-03T05:47:50+00:00

[ Upstream commit 377a879d9832f4ba69bd6a1fc996bb4181b1e504 ] retire_capture_urb() may print warning messages when the given URB doesn't align, and this may flood the system log easily. Put the rate limit to the message for avoiding it.

ALSA: usb-audio: Disable the quirk for Nura headset

2018-06-25T23:51:23+00:00

commit 5ebf6b1e459606d7fbf4fc67d2c28a6540953d93 upstream. The commit 33193dca671c ("ALSA: usb-audio: Add a quirk for Nura's first gen headset") added a quirk for Nura headset with USB ID 0a12:1243, with a hope that it doesn't conflict with others. Unfortunately, other devices (e.g. Philips Wecall) with the very same ID got broken by this change, spewing an error like: usb 2-1.8.2: 2:1: cannot set freq 48000 to ep 0x3 Until we find a proper solution, fix the regression at first by disabling the added quirk entry.

ALSA: usb-audio: Use Class Specific EP for UAC3 devices.

2018-05-15T05:29:10+00:00

bmAtributes offset doesn't exist in the UAC3 CS_EP descriptor. Hence, checking for pitch control as if it was UAC2 doesn't make any sense. Use the defined UAC3 offsets instead.

ALSA: usb: mixer: volume quirk for CM102-A+/102S+

2018-05-13T16:53:53+00:00

Currently it's not possible to set volume lower than 26% (it just mutes). Also fixes this warning: Warning! Unlikely big volume range (=9472), cval->res is probably wrong. [13] FU [PCM Playback Volume] ch = 2, val = -9473/-1/1 , and volume works fine for full range. Signed-off-by: Federico Cuello Cc: Signed-off-by: Takashi Iwai

ALSA: usx2y: Change return type to vm_fault_t

2018-04-25T06:15:20+00:00

Use new return type vm_fault_t for fault handler. For now, this is just documenting that the function returns a VM_FAULT value rather than an errno. Once all instances are converted, vm_fault_t will become a distinct type.

ALSA: usb-audio: Skip broken EU on Dell dock USB-audio

2018-04-24T11:39:30+00:00

The Dell Dock USB-audio device with 0bda:4014 is behaving notoriously bad, and we have already applied some workaround to avoid the firmware hiccup. Yet we still need to skip one thing, the Extension Unit at ID 4, which doesn't react correctly to the mixer ctl access.

ALSA: usb-audio: Fix missing endian conversion

2018-04-24T11:36:28+00:00

The UAC2 jack detection support introduced the bmControls checks in a couple of places, but they forgot the endian conversion; the bmControls of UAC2 terminal descriptor is __le16, not a byte like in UAC1.

ALSA: usb-audio: Fix forgotten conversion of control query functions

2018-04-23T14:20:29+00:00

The recent code refactoring made the argument for some helper functions to be the explicit UAC_CS_* and UAC2_CS_* value instead of 0-based offset. However, there was one place left forgotten, and it caused a regression on some devices appearing as the inconsistent mixer setup. This patch corrects the forgotten conversion.

ALSA: line6: Use correct endpoint type for midi output

2018-04-12T06:42:07+00:00

Sending MIDI messages to a PODxt through the USB connection shows "usb_submit_urb failed" in dmesg and the message is not received by the POD. The error is caused because in the funcion send_midi_async() in midi.c there is a call to usb_sndbulkpipe() for endpoint 3 OUT, but the PODxt USB descriptor shows that this endpoint it's an interrupt endpoint. Patch tested with PODxt only.
