snd_sb_qsound_destroy() contains the calls of removing the previously created mixer controls, but it doesn't clear the pointers. As snd_sb_qsound_destroy() itself may be repeatedly called via ioctl, this could lead to double-free potentially. Fix it by clearing the struct fields properly afterwards.

The handling of snd_ctl_new1() and snd_ctl_add() can be sometimes tricky, as snd_ctl_add() automatically removes the passed object at its error path. The recent fix addressed an overlooked issue that is relevant with that in SB driver code, and it can be a bit more simplified by assigning to a temporary variable, i.e. storing to the struct field only after the creation succeeds.

A lot of code for SB drivers is in a legacy style with assignment in if condition. This also made harder to catch some bugs (e.g. the commit 1c98f574 "ALSA: emu8000: Fix a use after free in snd_emu8000_create_mixer"). This patch fixes the coding style. All are rather simple conversions and there should be no functional changes. (The changes in snd_emu8000_new() for hw->res_port1, 2 and 3 are slightly different from the older ones, but this shouldn't matter much in practice.)

There are 2 issues on this machine, the 1st one is mic's plug/unplug can't be detected, that is because the mic is set to manual detecting mode, need to apply ALC255_FIXUP_XIAOMI_HEADSET_MIC to set it to auto detecting mode. The other one is headphone's plug/unplug can't be detected by pulseaudio, that is because the pulseaudio will use ucm2/sof-hda-dsp on this machine, and the ucm2 only handle 'Headphone Jack', but on this machine the headphone's pincfg sets the location to Front, then the alsa mixer name is "Front Headphone Jack" instead of "Headphone Jack", so override the pincfg to change location to Left.

In the workqueue to queue wake-up event, isochronous context is not processed, thus it's useless to check context for the workqueue to switch status of runtime for PCM substream to XRUN. On the other hand, in software IRQ context of 1394 OHCI, it's needed. This commit fixes the bug introduced when tasklet was replaced with workqueue.

The patch_realtek.c needs to check if the power_state.event equals PM_EVENT_SUSPEND, after using the direct-complete, the suspend() and resume() will be skipped if the codec is already rt_suspended, in this case, the patch_realtek.c will always get PM_EVENT_ON even the system is really resumed from S3. We could set power_state to PMSG_SUSPEND in the prepare(), if other PM functions are called before complete(), those functions will override power_state; if no other PM functions are called before complete(), we could know the suspend() and resume() are skipped since only S3 pm functions could be skipped by direct-complete, in this case set power_state to PMSG_RESUME in the complete(). This could guarantee the first time of calling hda_codec_runtime_resume() after complete() has the correct power_state.

snd_timer_notify1() calls the notification to each slave for a master event, but it passes a wrong event number. It should be +10 offset, corresponding to SNDRV_TIMER_EVENT_MXXX, but it's incorrectly with +100 offset. Casually this was spotted by UBSAN check via syzkaller.

The snd_ctl_led_sysfs_add and snd_ctl_led_sysfs_remove should contain the refcount operations in pair. However, snd_ctl_led_sysfs_remove fails to decrease the refcount to zero, which causes device_release never to be invoked. This leads to memory leak to some resources, like struct device_private. In addition, we also free some other similar memory leaks in snd_ctl_led_init/snd_ctl_led_exit. Fix this by replacing device_del to device_unregister in snd_ctl_led_sysfs_remove/snd_ctl_led_init/snd_ctl_led_exit. Note that, when CONFIG_DEBUG_KOBJECT_RELEASE is enabled, put_device will call kobject_release and delay the release of kobject, which will cause use-after-free when the memory backing the kobject is freed at once.

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.

The PCM delay accounting in USB-audio driver is a bit complex to follow, and this is an attempt to improve the readability and provide some potential fix. Basically, the PCM position delay is calculated from two factors: the in-flight data on URBs and the USB frame counter. For the playback stream, we advance the hwptr already at submitting URBs. Those "in-flight" data amount is now tracked, and this is used as the base value for the PCM delay correction. The in-flight data is decreased again at URB completion in return. For the capture stream, OTOH, there is no in-flight data, hence the delay base is zero. The USB frame counter is used in addition for correcting the current position. The reference frame counter is updated at each submission and receiving time, and the difference from the current counter value is taken into account. In this patch, each in-flight data bytes is recorded in the new snd_usb_ctx.queued field, and the total in-flight amount is tracked in snd_usb_substream.inflight_bytes field, as the replacement of last_delay field. Note that updating the hwptr after URB completion doesn't work for PulseAudio who tries to scratch the buffer on the fly; USB-audio is basically a double-buffer implementation, hence the scratching the buffer can't work for the already submitted data. So we always update hwptr beforehand. It's not ideal, but the delay account should give enough correctness. Link: https://lore.kernel.org/r/20210601162457.4877-4-tiwai@suse.deSigned-off-by:

This commit takes ALSA firewire-motu driver to perform sequence replay for media clock recovery. Unlike the other types of device, the devices in MOTU FireWire series require two levels of sequence replay; the sequence of the number of data blocks per packet and the sequence of source packet header per data block. The former is already cached by ALSA IEC 61883-1/6 packet streaming engine and ready to be replayed. The latter is also cached by ALSA firewire-motu driver itself with a previous patch. This commit takes the driver to replay both of them from the caches. The sequence replay is tested with below models: * 828 mkII * Traveler * UltraLite * 828 mk3 FireWire * 828 mk3 Hybrid (except for high sampling transfer frequency * UltraLite mk3 FireWire * 4pre * AudioExpress Unfortunately, below models still don't generate better sound, requires more work: * 8pre * 828 mk3 Hybrid at high sampling transfer frequency As long as I know, MOTU protocol version 1 requires extra care of the format of data block, thus below models are not supported yet in this time: * 828 * 896 Signed-off-by:

The devices in MOTU FireWire series put source packet header (SPH) into each data block of tx packet for presentation time of event. The format of timestamp is compliant to IEC 61883-1, with cycle and offset fields without sec field of 32 bit cycle time. This commit takes ALSA firewire-motu driver to cache the presentation time as offset from cycle in which the packet is transferred. Signed-off-by:
