since commit 57e6dae1 ("ALSA: usb-audio: do not trust too-big wMaxPacketSize values"), the expected packetsize is always limited to nominal + 25%. It was discovered, that some devices (Android audio accessory) have a much higher jitter in used packetsizes than 25% which would result in BABBLE condition and dropping of packets. A better solution is so assume the jitter to be the nominal packetsize: -one nearly empty packet followed by a almost 150% sized one. V2: changed to assume max frequency is +50 of nominal packetsize.

Some of userland applications call 'snd_pcm_hw_params()' and 'snd_pcm_hw_prepare()' sequentially, which means 'snd_pcm_hw_prepare()' is called twice and the second 'snd_pcm_hw_prepare()' is called in 'SNDRV_PCM_STATE_PREPARED' state. Some devices are not able to manage this and they will stop playback if the sample rate will be configured several times over USB protocol. V2: updated Changelog Signed-off-by:

The function returns -EINVAL even if it builds the stream properly. The bogus error code sneaked in during the code refactoring, but it wasn't noticed until now since the returned error code itself is ignored in anyway. Kill it here, but there is no behavior change by this patch, obviously. Fixes: e5779998 ('ALSA: usb-audio: refactor code') Signed-off-by:

Userspace apps have to claim USB interfaces before using endpoints in them (drivers/usb/core/devio.c:checkintf()). It's a lock mechanism so that two "drivers" don't steal data from each other. Kernel drivers don't have to claim interfaces to work - but they should, to lock out userspace. While there, fix line6_properties struct to match checkpatch.pl. Signed-off-by:

When the second call to load_asic_generic() fails in function load_asic(), "false" is returned. The real value of "false" is 0, which indicates success in the context. As a result, the execution status and the return value may be inconsistent. This patch fixes the bug. Bugzilla: https://bugzilla.kernel.org/show_bug.cgi?id=188761Signed-off-by:

I'm using an Alienware 15 R2 and had to use the alienware quirks to get my headphone output working. I fixed it by adding, SND_PCI_QUIRK(0x1028, 0x0708, "Alienware 15 R2 2016", QUIRK_ALIENWARE) to the patch. Signed-off-by:

More and more pin configurations have been adding to the pin quirk table, lots of them are only different from assoc and seq, but they all apply to the same QUIRK_FIXUP, if we don't compare assoc and seq when matching pin configurations, it will greatly reduce the pin quirk table size. We have tested this change on a couple of Dell laptops, it worked well. Cc: <stable@vger.kernel.org> Signed-off-by:

A modalias of 'ieee1394:ven00000D6Cmo00010060sp' hits units for M-Audio FireWire Audiophile only. However the unit has two states relevant to loaded firmware. Initial firmware returns 'FW Audiophile Bootloader', while functional firmware returns 'FW Audiophile'. ALSA bebob driver compares the units' model name to strings of 24 characters by the first 15 characters. This is shorter way to differentiate these two states but confusing to readers. This commit improves the code for this point. Kernel stack is consumed more in call of check_audiophile_booted() by a bit.

This patch is a cleanup of EMU1010 dock probing code in emu10k1 driver to use work instead of kthread in a loop. The work is lighter and easier to control than kthread, in general. Instead of a loop with the explicit sleep, we do simply delayed-schedule the work. At suspend/resume callbacks, the work is canceled and restarted, respectively. Signed-off-by: -
Takashi Iwai authored
The EMU1010 support in emu10k1 driver has two request_firmware() calls, one for the main board and one for the dock. Both call patterns are fairly similar, and we can simplify it by introducing a helper function and a table instead of the open switch/case. Signed-off-by: -
Takashi Iwai authored
The emu1010_firmware_thread() checks the previous dock status, but a wrong register is recorded as the last status when the dock is plugged in. Usually this isn't a big issue since this value gets overwritten by the next loop after one second. But when a dock is unplugged immediately after plugging, it means essentially missing undock handling. This patch addresses it by remembering the correct register value. Signed-off-by: -

The usb-audio driver implements the deferred device disconnection for the device in use. In this mode, the disconnection callback returns immediately while the actual ALSA card object removal happens later when all files get closed. As Shuah reported, this code flow, however, leads to a use-after-free, detected by KASAN: BUG: KASAN: use-after-free in snd_usb_audio_free+0x134/0x160 [snd_usb_audio] at addr ffff8801c863ce10 Write of size 8 by task pulseaudio/2244 Call Trace: [<ffffffff81b31473>] dump_stack+0x67/0x94 [<ffffffff81564ef1>] kasan_object_err+0x21/0x70 [<ffffffff8156518a>] kasan_report_error+0x1fa/0x4e0 [<ffffffff81564ad7>] ? kasan_slab_free+0x87/0xb0 [<ffffffff81565733>] __asan_report_store8_noabort+0x43/0x50 [<ffffffffa0fc0f54>] ? snd_usb_audio_free+0x134/0x160 [snd_usb_audio] [<ffffffffa0fc0f54>] snd_usb_audio_free+0x134/0x160 [snd_usb_audio] [<ffffffffa0fc0fb1>] snd_usb_audio_dev_free+0x31/0x40 [snd_usb_audio] [<ffffffff8243c78a>] __snd_device_free+0x12a/0x210 [<ffffffff8243d1f5>] snd_device_free_all+0x85/0xd0 [<ffffffff8242cae4>] release_card_device+0x34/0x130 [<ffffffff81ef1846>] device_release+0x76/0x1e0 [<ffffffff81b37ad7>] kobject_release+0x107/0x370 .....

It's the code trying to clear drvdata of the assigned usb_device where the usb_device itself was already released in usb_release_dev() after the disconnect callback. This patch fixes it by checking whether the code path is via the disconnect callback, i.e. chip->shutdown flag is set. Fixes: 79289e24 ('ALSA: usb-audio: Refer to chip->usb_id for quirks...')

The commit [1a3f0991: ALSA: hda - Fix surround output pins for ASRock B150M mobo] introduced a fixup of pin configs for ASRock mobos to fix the surround outputs. However, this overrides the pin configs of the mic pins as if they are outputs-only, effectively disabling the mic inputs. Of course, it's a regression wrt mic functionality. Actually the pins 0x18 and 0x1a don't need to be changed; we just need to disable the bogus pins 0x14 and 0x15. Then the auto-parser will pick up mic pins as switchable and assign the surround outputs there. This patch removes the incorrect pin overrides of NID 0x18 and 0x1a from the ASRock fixup.
