ALSA: usb-audio: Quirks for Gigabyte TRX40 Aorus Master onboard audio

2020-05-27T06:10:57Z

Gigabyte TRX40 Aorus Master is equipped with two USB-audio devices, a Realtek ALC1220-VB codec (USB ID 0414:a001) and an ESS SABRE9218 DAC (USB ID 0414:a000). The latter serves solely for the headphone output on the front panel while the former serves for the rest I/Os (mostly for the I/Os in the rear panel but also including the front mic). Both chips do work more or less with the unmodified USB-audio driver, but there are a few glitches. The ALC1220-VB returns an error for an inquiry to some jacks, as already seen on other TRX40-based mobos. However this machine has a slightly incompatible configuration, hence the existing mapping cannot be used as is. Meanwhile the ESS chip seems working without any quirk. But since both audio devices don't provide any specific names, both cards appear as "USB-Audio", and it's quite confusing for users. This patch is an attempt to overcome those issues: - The specific mapping table for ALC1220-VB is provided, reducing the non-working nodes and renaming the badly chosen controls. The connector map isn't needed here unlike other TRX40 quirks. - For both USB IDs (0414:a000 and 0414:a001), provide specific card name strings, so that user-space can identify more easily; and more importantly, UCM profile can be applied to each.

ALSA: usb-audio: mixer: volume quirk for ESS Technology Asus USB DAC

2020-05-26T06:30:35Z

The Asus USB DAC is a USB type-C audio dongle for connecting to the headset and headphone. The volume minimum value -23040 which is 0xa600 in hexadecimal with the resolution value 1 indicates this should be endianness issue caused by the firmware bug. Add a volume quirk to fix the volume control problem. Also fixes this warning: Warning! Unlikely big volume range (=23040), cval->res is probably wrong. [5] FU [Headset Capture Volume] ch = 1, val = -23040/0/1 Warning! Unlikely big volume range (=23040), cval->res is probably wrong. [7] FU [Headset Playback Volume] ch = 1, val = -23040/0/1 Signed-off-by: Chris Chiu Cc: Link: https://lore.kernel.org/r/20200526062613.55401-1-chiu@endlessm.com Signed-off-by: Takashi Iwai

ALSA: usb-audio: add mapping for ASRock TRX40 Creator

2020-05-04T06:23:57Z

This is another TRX40 based motherboard with ALC1220-VB USB-audio that requires a static mapping table. This motherboard also has a PCI device which advertises no codecs. The PCI ID is 1022:1487 and PCI SSID is 1022:d102. As this is using the AMD vendor ID, don't blacklist for now in case other boards have a working audio device with the same ssid. alsa-info.sh report for this board: http://alsa-project.org/db/?f=0a742f89066527497b77ce16bca486daccf8a70c Signed-off-by: Andrew Oakley Link: https://lore.kernel.org/r/20200503141639.35519-1-andrew@adoakley.name Signed-off-by: Takashi Iwai

ALSA: usb-audio: Fix usb audio refcnt leak when getting spdif

2020-04-23T07:10:05Z

snd_microii_spdif_default_get() invokes snd_usb_lock_shutdown(), which increases the refcount of the snd_usb_audio object "chip". When snd_microii_spdif_default_get() returns, local variable "chip" becomes invalid, so the refcount should be decreased to keep refcount balanced. The reference counting issue happens in several exception handling paths of snd_microii_spdif_default_get(). When those error scenarios occur such as usb_ifnum_to_if() returns NULL, the function forgets to decrease the refcnt increased by snd_usb_lock_shutdown(), causing a refcnt leak. Fix this issue by jumping to "end" label when those error scenarios occur.

ALSA: usb-audio: Add connector notifier delegation

2020-04-22T11:33:46Z

It turned out that ALC1220-VB USB-audio device gives the interrupt event to some PCM terminals while those don't allow the connector state request but only the actual I/O terminals return the request. The recent commit 7dc3c5a0172e ("ALSA: usb-audio: Don't create jack controls for PCM terminals") excluded those phantom terminals, so those events are ignored, too. My first thought was that this could be easily deduced from the associated terminals, but some of them have even no associate terminal ID, hence it's not too trivial to figure out. Since the number of such terminals are small and limited, this patch implements another quirk table for the simple mapping of the connectors. It's not really scalable, but let's hope that there will be not many such funky devices in future.

ALSA: usb-audio: Apply async workaround for Scarlett 2i4 2nd gen

2020-04-21T19:30:28Z

Due to rounding error driver sometimes incorrectly calculate next packet size, which results in audible clicks on devices with synchronous playback endpoints. For example on a high speed bus and a sample rate 44.1 kHz it loses one sample every ~40.9 seconds. Fortunately playback interface on Scarlett 2i4 2nd gen has a working explicit feedback endpoint, so we can switch playback data endpoint to asynchronous mode as a workaround.
