2022-05-24ALSA: usb-audio: Configure sync endpoints before dataCraig McLure
Devices such as the TC-Helicon GoXLR require the sync endpoint to be configured in advance of the data endpoint in order for sound output to work. This patch simply changes the ordering of EP configuration to resolve this.

2022-05-21ALSA: usb-audio: Add missing ep_idx in fixed EP quirksTakashi Iwai
The quirk entry for Focusrite Saffire 6 had no proper ep_idx for the capture endpoint, and this confused the driver, resulting in the broken sound. This patch adds the missing ep_idx in the entry. While we are at it, a couple of other entries (for Digidesign MBox and MOTU MicroBook II) seem to have the same problem, and those are covered as well.

2022-05-21ALSA: usb-audio: Workaround for clock setup on TEAC devicesTakashi Iwai
Maris reported that TEAC UD-501 (0644:8043) doesn't work with the typical "clock source 41 is not valid, cannot use" errors on the recent kernels. The currently known workaround so far is to restore (partially) what we've done unconditionally at the clock setup; namely, re-setup the USB interface immediately after the clock is changed. This patch re-introduces the behavior conditionally for TEAC devices. Further notes: - The USB interface shall be set later in snd_usb_endpoint_configure(), but this seems to be too late. - Even calling usb_set_interface() right after sne_usb_init_sample_rate() doesn't help; so this must be related with the clock validation, too. - The device may still spew the "clock source 41 is not valid" error at the first clock setup. This seems happening at the very first try of clock setup, but it disappears at later attempts. The error is likely harmless because the driver retries the clock setup (such an error is more or less expected on some devices).

2022-05-16ALSA: usb-audio: Refcount multiple accesses on the single clockTakashi Iwai
When a clock source is connected to multiple nodes / endpoints, the current USB-audio driver tries to set up at each time one of them is configured. Although it reads the current rate and updates only if it differs, some devices seem unhappy with this behavior and spew the errors when reading/updating the rate unnecessarily. This patch tries to reduce the redundant clock setup by introducing a refcount for each clock source. When the stream is actually running, a clock rate is "locked", and it bypasses the clock and/or refuse to change any longer.

2022-04-20ALSA: usb-audio: Clear MIDI port active flag after drainingTakashi Iwai
When a rawmidi output stream is closed, it calls the drain at first, then does trigger-off only when the drain returns -ERESTARTSYS as a fallback. It implies that each driver should turn off the stream properly after the drain. Meanwhile, USB-audio MIDI interface didn't change the port->active flag after the drain. This may leave the output work picking up the port that is closed right now, which eventually leads to a use-after-free for the already released rawmidi object. This patch fixes the bug by properly clearing the port->active flag after the output drain.

2022-04-13ALSA: usb-audio: Limit max buffer and period sizes per timeTakashi Iwai
In the previous fix, we increased the max buffer bytes from 1MB to 4MB so that we can use bigger buffers for the modern HiFi devices with higher rates, more channels and wider formats. OTOH, extending this has a concern that too big buffer is allowed for the lower rates, less channels and narrower formats; when an application tries to allocate as big buffer as possible, it'll lead to unexpectedly too huge size. Also, we had a problem about the inconsistent max buffer and period bytes for the implicit feedback mode when both streams have different channels. This was fixed by the (relatively complex) patch to reduce the max buffer and period bytes accordingly. This is an alternative fix for those, a patch to kill two birds with one stone (*): instead of increasing the max buffer bytes blindly and applying the reduction per channels, we simply use the hw constraints for the buffer and period "time". Meanwhile the max buffer and period bytes are set unlimited instead. Since the inconsistency of buffer (and period) bytes comes from the difference of the channels in the tied streams, as long as we care only about the buffer (and period) time, it doesn't matter; the buffer time is same for different channels, although we still allow higher buffer size. Similarly, this will allow more buffer bytes for HiFi devices while it also keeps the reasonable size for the legacy devices, too. As of this patch, the max period and buffer time are set to 1 and 2 seconds, which should be large enough for all possible use cases. (*) No animals were harmed in the making of this patch.

2022-04-08ALSA: usb-audio: Cap upper limits of buffer/period bytes for implicit fbTakashi Iwai
In the implicit feedback mode, some parameters are tied between both playback and capture streams. One of the tied parameters is the period size, and this can be a problem if the device has different number of channels to both streams. Assume that an application opens a playback stream that has an implicit feedback from a capture stream, and it allocates up to the max period and buffer size as much as possible. When the capture device supports only more channels than the playback, the minimum period and buffer sizes become larger than the sizes the playback stream took. That is, the minimum size will be over the max size the driver limits, and PCM core sees as if no available configuration is found, returning -EINVAL mercilessly. For avoiding this problem, we have to look through the counter part of audioformat list for each sync ep, and checks the channels. If more channels are found there, we reduce the max period and buffer sizes accordingly. You may wonder that the patch adds only the evaluation of channels between streams, and what about other parameters? Both the format and the rate are tied in the implicit fb mode, hence they are always identical.

2022-02-14ALSA: usb-audio: Don't abort resume upon errorsTakashi Iwai
The default mixer resume code treats the errors at restoring the modified mixer items as a fatal error, and it returns back to the caller. This ends up in the resume failure, and the device will be come unavailable, although basically those errors are intermittent and can be safely ignored. The problem itself has been present from the beginning, but it didn't hit usually because the code tries to resume only the modified items. But now with the recent commit to forcibly initialize each item at the probe time, the problem surfaced more often, hence it appears as a regression.

2021-11-16ALSA: usb-audio: Fix dB level of Bose Revolve+ SoundLinkTakashi Iwai
Bose Revolve+ SoundLink (0a57:40fa) advertises invalid dB level for the speaker volume. This patch provides the correction in the mixer map quirk table entry. Note that this requires the prerequisite change to add min_mute flag to the dB map table.

2021-11-16ALSA: usb-audio: Add minimal-mute notion in dB mapping tableTakashi Iwai
Some devices do mute the volume at the minimal volume, and for such devices, we need to set SNDRV_CTL_TLVT_DB_MINMAX_MUTE to the TLV information. It corresponds to setting usb_mixer_elem_info.min_mute flag in the USB-audio driver. This patch adds a new field min_mute in usbmix_dB_map so that the mixer map entry can pass the flag.

2021-11-01ALSA: usb-audio: Line6 HX-Stomp XL USB_ID for 48k-fixed quirkJason Ormes
Adding the Line6 HX-Stomp XL USB_ID as it needs this fixed frequency quirk as well. The device is basically just the HX-Stomp with some more buttons on the face. I've done some recording with it after adding it, and it seems to function properly with this fix. The Midi features appear to be working as well.

2021-10-27ALSA: ua101: fix division by zero at probeJohan Hovold
Add the missing endpoint max-packet sanity check to probe() to avoid division by zero in alloc_stream_buffers() in case a malicious device has broken descriptors (or when doing descriptor fuzz testing). Note that USB core will reject URBs submitted for endpoints with zero wMaxPacketSize but that drivers doing packet-size calculations still need to handle this (cf. commit 2548288b4fb0 ("USB: Fix: Don't skip endpoint descriptors with maxpacket=0")).

2021-10-19ALSA: usb-audio: Fix microphone sound on Jieli webcam.Marco Giunta
When a Jieli Technology USB Webcam is connected, the video part works well, but the mic sound is speeded up. On dmesg there are messages about different rates from the runtime rates, warnings about volume resolution and lastly, the log is filled, every 5 seconds, with retire_capture_urb error messages. The mic works only when ep packet size is set to wMaxPacketSize (normal sound and no more retire_capture_urb error messages). Skipping reading sample rate, fixes the messages about different rates and forcing a volume resolution, fixes warnings about volume range. I have arbitrarily choosed the value (16): I read in a comment that there should be no more than 255 levels, so 4096 (max volume) / 16 = 0-255.

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.
