2020-08-10ALSA: usb-audio: work around streaming quirk for MacroSilicon MS2109Hector Martin1-0/+3
Further investigation of the L-R swap problem on the MS2109 reveals that the problem isn't that the channels are swapped, but rather that they are swapped and also out of phase by one sample. In other words, the issue is actually that the very first frame that comes from the hardware is a half-frame containing only the right channel, and after that everything becomes offset. So introduce a new quirk field to drop the very first 2 bytes that come in after the format is configured and a capture stream starts. This puts the channels in phase and in the correct order.

2020-03-06ALSA: usb-audio: Add support for MOTU MicroBook IIcAlexander Tsoy1-1/+17
MicroBook IIc operates in UAC2 mode by default. This patch addresses several issues with it: - MicroBook II and IIc shares the same USB ID. We can distinguish them by interface class. - MaxPacketsOnly attribute is erroneously set in endpoint descriptors. As a result this card produces noise with all sample rates other than 96 KHz. This also causes issues like IOMMU page faults and other problems with host controller. - Sample rate changes takes more than 2 seconds for this device. Clock validity request returns false during that period, so the clock validity quirk is required.

The Audioengine D1 (0x2912:0x30c8) does support reading the sample rate, but it returns the rate in byte-reversed order. When setting sampling rate, the driver produces these warning messages: [168840.944226] usb 3-2.2: current rate 4500480 is different from the runtime rate 44100 [168854.930414] usb 3-2.2: current rate 8436480 is different from the runtime rate 48000 [168905.185825] usb 3-2.1.2: current rate 30465 is different from the runtime rate 96000 As can be seen from the hexadecimal conversion, the current rate read back is byte-reversed from the rate that was set. 44100 == 0x00ac44, 4500480 == 0x44ac00 48000 == 0x00bb80, 8436480 == 0x80bb00 96000 == 0x017700, 30465 == 0x007701 Rather than implementing a new quirk to reverse the order, just skip checking the rate to avoid spamming the log.

Add delay to make sure that audio urbs are not sent too early. Otherwise the device hangs. Windows driver makes ~2s delay, so use about the same time delay value. snd_usb_apply_boot_quirk() is called 3 times for my MOTU M4, which is an overkill.

2019-12-18ALSA: usb-audio: set the interface format after resume on Dell WD19Hui Wang1-0/+11
Recently we found the headset-mic on the Dell Dock WD19 doesn't work anymore after s3 (s2i or deep), this problem could be workarounded by closing (pcm_close) the app and then reopening (pcm_open) the app, so this bug is not easy to be detected by users. When problem happens, retire_capture_urb() could still be called periodically, but the size of captured data is always 0, it could be a firmware bug on the dock. Anyway I found after resuming, the snd_usb_pcm_prepare() will be called, and if we forcibly run set_format() to set the interface and its endpoint, the capture size will be normal again. This problem and workaound also apply to playback. To fix it in the kernel, add a quirk to let set_format() run forcibly once after resume.

2019-03-01ALSA: usb-audio: Add quirk for MOTU MicroBook IIManuel Reinhardt1-0/+101
Add an entry to the quirks-table to for usb-audio to recognize the Microbook II (although it only exposes vendor interfaces). A simple boot quirk is also implemented to set up the sample rate and make sure that no audio urbs are sent before the device is ready. This patch only provides audio playback and capture at 96kHz sample rate. Notice the following shortcomings: - The sample rate is currently hardcoded to 96k although the device also supports 48k and 44.1k. - The various mixer controls of the MicroBook are not made available. - The keep-iface control should be on by default because the device shuts down whenever the altsetting is reset which is usually unwanted. (I don't know the best way to do this) - The communication format used by the MicroBook for sample rate setting and also other setup has been reverse engineered by looking at the usbmon output while running the windows driver through virtualbox. In this patch the first byte of every message is set to \0 while in the observed communications the first byte acts as a "message-counter" increasing its value with every message sent. Leaving it at \0 does not seem to affect the device. Signed-off-by: Manuel Reinhardt <manuel.rhdt@gmail.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>

2018-11-06ALSA: usb-audio: Define registers for CM6206Linus Walleij1-5/+124
The register map for CM6206 is known and we can define what the values written to the different registers actually mean. I tested to print the hex values before/after this change, there is no functional change. Signed-off-by: Linus Walleij <linus.walleij@linaro.org> Signed-off-by: Takashi Iwai <tiwai@suse.de>
2018-07-27ALSA: usb-audio: quirks: Replace mdelay() with msleep() and usleep_range()Jia-Ju Bai1-7/+7
snd_usb_select_mode_quirk(), snd_usb_set_interface_quirk() and snd_usb_ctl_msg_quirk() are never called in atomic context. They call mdelay() to busily wait, which is not necessary. mdelay() can be replaced with msleep() and usleep_range(). This is found by a static analysis tool named DCNS written by myself.

2018-07-26ALSA: usb-audio: Add support for Encore mDSD USB DACJeff Crukley1-0/+1
This patch adds native DSD playback support for the Encore mDSD USB DAC by specifying the vendor and product ID's Signed-off-by: Jeff Crukley <jcrukley@gmail.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>
2018-07-23ALSA: usb-audio: Generic DSD detection for Thesycon-based implementationsYue Wang1-0/+1
Thesycon provides solutions to XMOS chips, and has its own device vendor id. In this patch, we use generic method to detect DSD capability of Thesycon-based UAC2 implementations in order to support a wide range of current and future devices. The patch will enable the SNDRV_PCM_FMTBIT_DSD_U32_BE bit for the DAC hence enable native DSD playback up to DSD512 format.

2018-06-13ALSA: usb-audio: Generic DSD detection for XMOS-based implementationsJussi Laako1-2/+1
Use more generic method to detect DSD capability of XMOS-based UAC2 implementations in order to support future devices without having to explicitly list every device separately. Signed-off-by: Jussi Laako <jussi@sonarnerd.net> Signed-off-by: Takashi Iwai <tiwai@suse.de>
2018-06-13ALSA: usb-audio: Add native DSD support for Mytek DACsJussi Laako1-0/+13
Add new mostly generic code with Mytek VID to support native DSD mode. This implementation should be easier to maintain when manufacturers release new products. Signed-off-by: Jussi Laako <jussi@sonarnerd.net> Signed-off-by: Takashi Iwai <tiwai@suse.de>
