2016-08-29ALSA: usb-audio: Add sample rate inquiry quirk for B850V3 CP2114Ken Lin
Avoid getting sample rate on B850V3 CP2114 as it is unsupported and causes noisy "current rate is different from the runtime rate" messages when playback starts.

2016-08-22ALSA: usb: fine-tune Tenor error compensation valueDaniel Mack
Users of devices affected by the Tenor feedback data error report buffer underruns, even with the +/- 0x1.0000 quirk applied. Compensating the error with 0xf000 instead seems to reliably fix that issue.

2016-08-22ALSA: usb: use TEAC UD-H01 quirk for more devicesDaniel Mack
The quirk seems to be necessary not only for TEAC UD-H01 devices, but to more that are based on the Tenor 8802TL chipset. Devices built by T+A are affected too, and they apparently all use the same USB PID:PID. Extend the quirky handling for that device as well, and rename the quirks flag.

2016-04-29ALSA: usb-audio: Limit retrying sample rate readsTakashi Iwai
There are many USB audio devices with buggy firmware that don't react with the sample rate reading properly. This often results in the flood of error messages and slowing down the operation. The sample rate read back is basically only for confirming the sample rate setup, and it's not critically important. As a compromise, in this patch, we stop the sample rate read back once when the device gives errors more than tolerance (twice, as of now). This should improve most of error cases while we still can catch the firmware bugginess. Signed-off-by: Takashi Iwai <tiwai@suse.de>

This is Dell usb dock audio workaround. It was fixed the master volume keep lower. [Some background: the patch essentially skips the controls of a couple of FU volumes. Although the firmware exposes the dB and the value information via the usb descriptor, changing the values (we set the min volume as default) screws up the device. Although this has been fixed in the newer firmware, the devices are shipped with the old firmware, thus we need the workaround in the driver side. -- tiwai] Signed-off-by: Kailang Yang <kailang@realtek.com> Cc: <stable@vger.kernel.org> Signed-off-by: Takashi Iwai <tiwai@suse.de>
2016-04-09ALSA: usb-audio: allow clock source validity interruptsDaniel Mack
miniDSP USBStreamer UAC2 devices send clock validity changes with the control field set to zero. The current interrupt handler ignores all packets if the control field does not match the mixer element's, but it really should only do that in case that field is needed to distinguish multiple elements with the same ID. This patch implements a logic that lets notifications packets pass if the element ID is unique for a given device.

2016-04-09ALSA: usb-audio: add UAC2 clock sources as mixer controlsDaniel Mack
UAC2 specifies clock sources that optionally have validity controls. This patch exposes them as mixer controls, so they can be read (and at least in theory even be written) by userspace applications in order to make clock selection policy decisions. This implementation does nothing if the device is not UAC2 compliant, or if the clock source does not define said validity control bits. Tested with a miniDSP USBStreamer (0x2752/0x0016).

2016-03-31ALSA: usb-audio: Fix double-free in error paths after ↵Vladis Dronov
snd_usb_add_audio_stream() call create_fixed_stream_quirk(), snd_usb_parse_audio_interface() and create_uaxx_quirk() functions allocate the audioformat object by themselves and free it upon error before returning. However, once the object is linked to a stream, it's freed again in snd_usb_audio_pcm_free(), thus it'll be double-freed, eventually resulting in a memory corruption. This patch fixes these failures in the error paths by unlinking the audioformat object before freeing it.

2016-03-03[media] sound/usb: Use Media Controller API to share media resourcesShuah Khan
Change ALSA driver to use Media Controller API to share media resources with DVB and V4L2 drivers on a AU0828 media device. Media Controller specific initialization is done after sound card is registered. ALSA creates Media interface and entity function graph nodes for Control, Mixer, PCM Playback, and PCM Capture devices. snd_usb_hw_params() will call Media Controller enable source handler interface to request the media resource. If resource request is granted, it will release it from snd_usb_hw_free(). If resource is busy, -EBUSY is returned. Media specific cleanup is done in usb_audio_disconnect().

2016-03-01ALSA: usb-audio: Add a quirk for Plantronics DA45Dennis Kadioglu
Plantronics DA45 does not support reading the sample rate which leads to many lines of "cannot get freq at ep 0x4" and "cannot get freq at ep 0x84". This patch adds the USB ID of the DA45 to quirks.c and avoids those error messages.

2016-02-13ALSA: usb-audio: avoid freeing umidi object twiceAndrey Konovalov
The 'umidi' object will be free'd on the error path by snd_usbmidi_free() when tearing down the rawmidi interface. So we shouldn't try to free it in snd_usbmidi_create() after having registered the rawmidi interface. Found by KASAN.

2016-01-29ALSA: usb-audio: Add quirk_alias optionTakashi Iwai
This patch adds a new option "quirk_alias" to snd-usb-audio driver for allowing user to pass the quirk alias list. A quirk alias consists of a string form like 0123abcd:5678beef, which makes to apply a quirk to a device with USB ID 0123:abcd treated as if it were 5678:beef. This feature is useful to test an existing quirk, typically for a newer model of the same vendor, without patching / rebuilding the kernel driver. The current implementation is fairly simplistic: since there is no API for matching a usb_device_id to the given ID pair, it has an open code to loop over the id table and matches only with vendor:product pair. So far, this is OK, as all existing entries are with vendor:product pairs, indeed. Once when we have another matching entry, however, we'd need to update get_alias_quirk() as well. Note that this option is provided only for testing / development. If you want to have a proper support, contact to upstream for adding the matching quirk in the driver code statically.
