[PATCH v2 0/1] ALSA: hda/realtek - Fix silent output on Gigabyte X570 Aorus Master after reboot from Windows
by Christian Lachner 03 Jan '22

03 Jan '22

This is version 2 of my patch. It implements suggestions from Takashi Iwai. Thanks for that! Furthermore, I re-analyzed all the relevant coefs and removed those that are not actually needed. === This patch addresses an issue where after rebooting from Windows into Linux there would be no audio output. It turns out that the Realtek Audio driver on Windows changes some coeffs which are not being reset/reinitialized when rebooting the machine. As a result, there is no audio output until these coeffs are being reset to their initial state. This patch takes care of that by setting known-good (initial) values to the coeffs. The coeffs were collected via alsa-info, see: broken: https://pastebin.com/4bRBSseH working: https://pastebin.com/WUTufvZB I also created a script which fixes the audio at runtime. #!/bin/sh hda-verb /dev/snd/hwC2D0 0x20 SET_COEF_INDEX 0x1a hda-verb /dev/snd/hwC2D0 0x20 SET_PROC_COEF 0x01c1 hda-verb /dev/snd/hwC2D0 0x20 SET_COEF_INDEX 0x1b hda-verb /dev/snd/hwC2D0 0x20 SET_PROC_COEF 0x0202 hda-verb /dev/snd/hwC2D0 0x20 SET_COEF_INDEX 0x43 hda-verb /dev/snd/hwC2D0 0x20 SET_PROC_COEF 0x3005 However, obviously, we can and should fix this in the kernel. We initially relied upon alc1220_fixup_clevo_p950() to fix some pins in the connection list. However, it also sets coef 0x7 which does not need to be touched. Furthermore, to prevent mixing device-specific quirks I introduced a new alc1220_fixup_gb_x570() which is heavily based on alc1220_fixup_clevo_p950() but does not set coeff 0x7 and fixes the coeffs that are actually needed instead. This new alc1220_fixup_gb_x570() is believed to also work for other boards, like the Gigabyte X570 Aorus Extreme and the newer Gigabyte Aorus X570S Master. However, as there is no way for me to test these I initially only enable this new behaviour for the mainboard I have which is the Gigabyte X570(non-S) Aorus Master. I tested this patch on the 5.15 branch as well as on master and it is working well for me.

[RESEND] Amlogic DPCM audio card(s) speaker placement issue
by Christian Hewitt 03 Jan '22

03 Jan '22

Hello alsa-dev people, I’d like to describe a problem with speaker placement seen with the Amlogic (meson) AIU and AXG drivers when playing multi-channel media. The problem was traced to a failure to get the channel map via snd_pcm_get_chmap() and further analysis showed this failed because the PCM controls are exposed on a different device than the PCM stream. e.g. on LibreTech LePotato with DPCM routing configured for HDMI output, the hw PCM is on the single frontend device 0 but the PCM controls are on device 2: LePotato:~ # aplay -l **** List of PLAYBACK Hardware Devices **** card 0: LIBRETECHCC [LIBRETECH-CC], device 0: fe.dai-link-0 (*) [] Subdevices: 1/1 Subdevice #0: subdevice #0 LePotato:~ # amixer controls numid=19,iface=MIXER,name='PCM Playback Volume' numid=18,iface=MIXER,name='ACODEC Left DAC Sel' numid=7,iface=MIXER,name='ACODEC Mute Ramp Switch' numid=2,iface=MIXER,name='ACODEC Playback Channel Mode' numid=3,iface=MIXER,name='ACODEC Playback Switch' numid=4,iface=MIXER,name='ACODEC Playback Volume' numid=5,iface=MIXER,name='ACODEC Ramp Rate' numid=17,iface=MIXER,name='ACODEC Right DAC Sel' numid=8,iface=MIXER,name='ACODEC Unmute Ramp Switch' numid=6,iface=MIXER,name='ACODEC Volume Ramp Switch' numid=1,iface=MIXER,name='AIU ACODEC I2S Lane Select' numid=16,iface=MIXER,name='AIU ACODEC OUT EN Switch' numid=15,iface=MIXER,name='AIU ACODEC SRC' numid=14,iface=MIXER,name='AIU HDMI CTRL SRC' numid=13,iface=MIXER,name='AIU SPDIF SRC SEL' numid=12,iface=PCM,name='ELD',device=2 numid=11,iface=PCM,name='IEC958 Playback Default',device=2 numid=10,iface=PCM,name='IEC958 Playback Mask',device=2 numid=9,iface=PCM,name='Playback Channel Map',device=2 https://github.com/torvalds/linux/blob/master/arch/arm64/boot/dts/amlogic/m… or on a Wetek Play 2: WP2:~ # aplay -l **** List of PLAYBACK Hardware Devices **** card 0: WETEKPLAY2 [WETEK-PLAY2], device 0: fe.dai-link-0 (*) [] Subdevices: 1/1 Subdevice #0: subdevice #0 card 0: WETEKPLAY2 [WETEK-PLAY2], device 1: fe.dai-link-1 (*) [] Subdevices: 1/1 Subdevice #0: subdevice #0 WP2:~ # amixer controls numid=7,iface=MIXER,name='PCM Playback Volume' numid=6,iface=MIXER,name='AIU HDMI CTRL SRC' numid=5,iface=MIXER,name='AIU SPDIF SRC SEL' numid=4,iface=PCM,name='ELD',device=4 numid=3,iface=PCM,name='IEC958 Playback Default',device=4 numid=2,iface=PCM,name='IEC958 Playback Mask',device=4 numid=1,iface=PCM,name='Playback Channel Map',device=4 https://github.com/torvalds/linux/blob/master/arch/arm64/boot/dts/amlogic/m… It looks like the PCM controls of the backend hdmi-codec are not routed through the DPCM driver the same way as PCM streams. We discussed that issue with Jerome, the driver author, but it’s not clear which bits we are missing. i.e. if it's something ASoC DPCM should be handling or if some further plumbing in the card driver or userspace is needed? Any hints into the right direction would be highly appreciated! Christian

slow snd_rawmidi_drain() for VirMidi devcies
by Stefan Sauer 02 Jan '22

02 Jan '22

hi, happy new year every one. During the free days I've tried to link BitwigStudio to the webapp [1]cables.gl over virmidi. Unfortunately Bitwig Studio only supports rawmidi. What I discovered is that there is a strange slowness when sending data to virmidi caused by snd_rawmidi_drain(). I've posted two tiny, self-contained c apps to: [2]https://gist.github.com/ensonic/c7588b87fa6c1fa94a8f753b1e0aa394 See some examples below. 2 observations: * snd_rawmidi_type() is *not* reporting virmidi as VIRTUAL * snd_rawmidi_drain() takes about 60ms! on virtual vs. less that 0.1 ms on usb midi (I checked all my hw midi and the worst was avg=1ms on physical midi image unitor8) When comparing the implementations: [3]https://github.com/alsa-project/alsa-lib/blob/master/ src/rawmidi/rawmidi_virt.c#L173 [4]https://github.com/alsa-project/alsa-lib/blob/master/ src/rawmidi/rawmidi_hw.c#L164 I see that the hw one results in an IOCTL (SNDRV_RAWMIDI_IOCTL_DRAIN) which I can see when strac'ing app and I wonder if this is the root cause? Why is rawmidi_virt.c not used for virmidi? From poking at snd_rawmidi_open_conf() I have not yet figured where this is decided .... If the IOCTl is the right code path, any idea why it is slow? Is the virmidi driver not reporting buffer fill status or something like that?
