2021-10-27ALSA: usb-audio: Provide quirk for Sennheiser GSP670 HeadsetBrendan Grieve
commit 3c414eb65c294719a91a746260085363413f91c1 upstream. As per discussion at: https://github.com/szszoke/sennheiser-gsp670-pulseaudio-profile/issues/13 The GSP670 has 2 playback and 1 recording device that by default are detected in an incompatible order for alsa. This may have been done to make it compatible for the console by the manufacturer and only affects the latest firmware which uses its own ID. This quirk will resolve this by reordering the channels.

commit 48827e1d6af58f219e89c7ec08dccbca28c7694e upstream. The device advertises 8 formats, but only a rate of 48kHz is honored by the hardware and 24 bits give chopped audio, so only report the one working combination. This fixes out-of-the-box audio experience with PipeWire which otherwise attempts to choose S24_3LE (while PulseAudio defaulted to S16_LE).

2021-10-17ALSA: usb-audio: Unify mixer resume and reset_resume procedureTakashi Iwai
[ Upstream commit 7b9cf9036609428e845dc300aec13822ba2c4ab3 ] USB-audio driver assumes that the normal resume would preserve the device configuration while reset_resume wouldn't, and tries to restore the mixer elements only at reset_resume callback. However, this seems too naive, and some devices do behave differently, resetting the volume at the normal resume; this resulted in the inconsistent volume that surprised users. This patch changes the mixer resume code to handle both the normal and reset resume in the same way, always restoring the original mixer element values. This allows us to unify the both callbacks as well as dropping the no longer used reset_resume field, which ends up with a good code reduction. A slight behavior change by this patch is that now we assign restore_mixer_value() as the default resume callback, and the function is no longer called at reset-resume when the resume callback is overridden by the quirk function. That is, if needed, the quirk resume function would have to handle similarly as restore_mixer_value() by itself.

[ Upstream commit 4801bee7d5a36c199b734a28cde5259183aff822 ] For making user to switch back to the old playback mode, this patch adds a new module option 'lowlatency' to snd-usb-audio driver. When user face a regression due to the recent low-latency playback support, they can test easily by passing lowlatency=0 option without rebuilding the kernel.

2021-09-08ALSA: usb-audio: Work around for XRUN with low latency playbackTakashi Iwai
commit 4267c5a8f3133db0572cd9abee059b42cafbbdad upstream. The recent change for low latency playback works in most of test cases but it turned out still to hit errors on some use cases, most notably with JACK with small buffer sizes. This is because USB-audio driver fills up and submits full URBs at the beginning, while the URBs would return immediately and try to fill more -- that can easily trigger XRUN. It was more or less expected, but in the small buffer size, the problem became pretty obvious. Fixing this behavior properly would require the change of the fundamental driver design, so it's no trivial task, unfortunately. Instead, here we work around the problem just by switching back to the old method when the given configuration is too fragile with the low latency stream handling. As a threshold, we calculate the total buffer bytes in all plus one URBs, and check whether it's beyond the PCM buffer bytes. The one extra URB is needed because XRUN happens at the next submission after the first round.

2021-09-08ALSA: usb-audio: Fix regression on Sony WALKMAN NW-A45 DACTakashi Iwai
commit 7af5a14371c1cf94a41f08eabb62a3faceec8911 upstream. We've got a regression report for USB-audio with Sony WALKMAN NW-A45 DAC device where no sound is audible on recent kernel. The bisection resulted in the code change wrt endpoint management, and the further debug session revealed that it was caused by the order of the USB audio interface. In the earlier code, we always set up the USB interface at first before other setups, but it was changed to be done at the last for UAC2/3, which is more standard way, while keeping the old way for UAC1. OTOH, this device seems requiring the setup of the interface at first just like UAC1. This patch works around the regression by applying the interface setup specifically for the WALKMAN at the beginning of the endpoint setup procedure. This change is written straightforwardly to be easily backported in old kernels. A further cleanup to move the workaround into a generic quirk section will follow in a later patch.

2021-07-24ALSA: usb-audio: fix incorrect clock source settingchihhao.chen
The following scenario describes an echo test for Samsung USBC Headset (AKG) with VID/PID (0x04e8/0xa051). We first start a capture stream(USB IN transfer) in 96Khz/24bit/1ch mode. In clock find source function, we get value 0x2 for clock selector and 0x1 for clock source. Kernel-4.14 behavior Since clock source is valid so clock selector was not set again. We pass through this function and start a playback stream(USB OUT transfer) in 48Khz/32bit/2ch mode. This time we get value 0x1 for clock selector and 0x1 for clock source. Finally clock id with this setting is 0x9. Kernel-5.10 behavior Clock selector was always set one more time even it is valid. When we start a playback stream, we will get 0x2 for clock selector and 0x1 for clock source. In this case clock id becomes 0xA. This is an incorrect clock source setting and results in severe noises. We see wrong data rate in USB IN transfer. (From 288 bytes/ms becomes 144 bytes/ms) It should keep in 288 bytes/ms. This earphone works fine on older kernel version load because this is a newly-added behavior.

2021-07-07ALSA: usb-audio: Reduce latency at playback start, take#2Takashi Iwai
This is another attempt for the reduction of the latency at the start of a USB audio playback stream. The first attempt in the commit 9ce650a75a3b caused an unexpected regression (a deadlock with pipewire usage) and was later reverted by the commit 4b820e167bf6. The devils are always living in details, of course; the cause of the deadlock was the call of snd_pcm_period_elapsed() inside prepare_playback_urb() callback. In the original code, this callback is never called from the stream lock context as it's driven solely from the URB complete callback. Along with the movement of the URB submission into the trigger START, this prepare call may be also executed in the stream lock context, hence it deadlocked with the another lock in snd_pcm_period_elapsed(). (Note that this happens only conditionally with a small period size that matches with the URB buffer length, which was a reason I overlooked during my tests. Also, the problem wasn't seen in the capture stream because the capture stream handles the period-elapsed only at retire callback that isn't executed at the trigger.) If it were only about avoiding the deadlock, it'd be possible to use snd_pcm_period_elapsed_under_stream_lock() as a solution. However, in general, the period elapsed notification must be sent after the actual stream start, and replacing the call wouldn't satisfy the pattern. A better option is to delay the notification after the stream start procedure finished, instead. In the case of USB framework, one of the fitting place would be the complete callback of the first URB. So, as a workaround of the deadlock and the order fixes above, in addition to the re-applying the changes in the commit 9ce650a75a3, this patch introduces a new flag indicating the delayed period-elapsed handling and sets it under the possible deadlock condition (i.e. prepare callback being called before subs->running is set). Once when the flag is set, the period-elapsed call is handled at a later URB complete call instead. As a reference for the original motivation for the low-latency change, I cite here again: | USB-audio driver behaves a bit strangely for the playback stream -- | namely, it starts sending silent packets at PCM prepare state while | the actual data is submitted at first when the trigger START is | kicked off. This is a workaround for the behavior where URBs are | processed too quickly at the beginning. That is, if we start | submitting URBs at trigger START, the first few URBs will be | immediately completed, and this would result in the immediate | period-elapsed calls right after the start, which may confuse | applications. | | OTOH, submitting the data after silent URBs would, of course, result | in a certain delay of the actual data processing, and this is rather | more serious problem on modern systems, in practice. | | This patch tries to revert the workaround and lets the URB | submission starting at PCM trigger for the playback again. As far | as I've tested with various backends (native ALSA, PA, JACK, PW), I | haven't seen any problems (famous last words :) | | Note that the capture stream handling needs no such workaround, | since the capture is driven per received URB.

At least occasionally one of the watchdog call traces was Call Trace: _raw_spin_lock_irqsave+0x35/0x40 snd_pcm_period_elapsed+0x1b/0xa0 [snd_pcm] snd_usb_endpoint_start+0x1a0/0x3c0 [snd_usb_audio] start_endpoints+0x23/0x90 [snd_usb_audio] snd_usb_substream_playback_trigger+0x7b/0x1a0 [snd_usb_audio] snd_pcm_common_ioctl+0x1c44/0x2360 [snd_pcm] snd_pcm_ioctl+0x2e/0x40 [snd_pcm] __se_sys_ioctl+0x72/0xc0 do_syscall_64+0x4c/0xa0 entry_SYSCALL_64_after_hwframe+0x44/0xae so presumably it's a locking error on that substream spinlock that snd_pcm_period_elapsed() takes.

It appears the intention was to cast the void pointer to a u16 pointer so that the data could be iterated through like an array of u16 values. However, the cast happens after the increment because a cast is an rvalue, whereas the post-increment operator only works on lvalues, so the loop does not iterate as expected. This is not a bug in practice because count is not greater than one at the moment but this could change in the future so this should be fixed. Replace the cast with a temporary variable of the proper type, which is less error prone and fixes the iteration. Do the same thing for the 'u8 *' below this if block.

2021-06-22ALSA: usb-audio: scarlett2: Fix wrong resume callTakashi Iwai
The current way of the scarlett2 mixer code managing the usb_mixer_elem_info object is wrong in two ways: it passes its internal index to the head.id field, and the val_type field is uninitialized. This ended up with the wrong execution at the resume because a bogus unit id is passed wrongly. Also, in the later code extensions, we'll have more mixer elements, and passing the index will overflow the unit id size (of 256). This patch corrects those issues. It introduces a new value type, USB_MIXER_BESPOKEN, which indicates a non-standard mixer element, and use this type for all scarlett2 mixer elements, as well as initializing the fixed unit id 0 for avoiding the overflow.
