[PATCH] ALSA: intel_hdmi: Check for error num after setting mask
by Jiasheng Jiang 06 Jan '22

06 Jan '22

As the dma_supported() may fail, the dma_set_mask_and_coherent() may fail too. Therefore, it should be better to check it and return error if fails.

alsa-project/alsa-utils issue #134 was opened from kosiu: I know that hda-analyzer is not a part of alsa-utils. I'm trying to port it into GTK3 at first but I encounter problems with scrolling of the graph.

UAC2: are UAC2 latency controls included in snd_pcm_status_get_delay?
by Pavel Hofman 06 Jan '22

06 Jan '22

Hi, The UAC2 ch. "5.2.4.8 Latency Control" specifies latencies optionally reported by the device for individual entities. Especially the overall terminal latency TE_LATENCY_CONTROL is interesting. Some video players include the delay reported by snd_pcm_status_get_delay into their AV sync calculation. A linux USB audio gadget can perform some advanced DSP, which including the output device latency can result in a non-negligible overall latency. The gadget userspace software could configure the actual value to be reported by the gadget to the host in the selector UAC2_TE_LATENCY (audio_v2.h). The UAC2-specced max value of over 4 secs is more than sufficient for standard use cases. But I could not find any read of the UAC2_TE_LATENCY control selector in the snd-usb-audio driver ( https://elixir.bootlin.com/linux/latest/C/ident/UAC2_TE_LATENCY ). Please does the driver include this value into the overall delay reported through alsa-lib? If not, would it make sense to add such support? Thanks a lot, Pavel.

[PATCH] ALSA: hda: ALC287: Add Lenovo IdeaPad Slim 9i 14ITL5 speaker quirk
by Bart Kroon 05 Jan '22

05 Jan '22

Hello, The speaker fixup that is used for the Yoga 7 14ITL5 also applies to the IdeaPad Slim 9i 14ITL5. The attached patch applies the quirk to initialise the amplifier on the IdeaPad Slim 9i as well. This is validated to work on my laptop. Signed-off-by: Bart Kroon <bart(a)tarmack.eu> Regards, Bart

[PATCH] ASoC: ak4375: Fix unused function error
by Takashi Iwai 05 Jan '22

A randconfig caught a compile warning that is now treated as a fatal error: sound/soc/codecs/ak4375.c:415:13: error: ‘ak4375_power_off’ defined but not used [-Werror=unused-function] where ak4375_power_off() is used only from the PM handler.

Handling SIGTSTP (Ctrl+Z) /SIGCONT/fg with aplay/cplay
by Daniel Baluta 05 Jan '22

05 Jan '22

Hi all, Is there any quick document for handling Ctrl + Z with aplay/cplay? I don't see this signal handled with alsa-lib or tinycompress although linux kernel offers PAUSE/RESUME ioctls. What should be the expected behavior? thanks, Daniel.

[PATCH 0/8] Add low power hibernation support to cs35l41
by Charles Keepax 05 Jan '22

05 Jan '22

This patch series adds support for the low power hibernation feature on cs35l41. This allows the DSP memory to be retained whilst the device enters a very low power state. Patches 1-6 can happily be applied straight away and are mostly bug fixes to set things up for the series specifically around getting the cache handling corrected in the driver. Patches 7,8 specifically will cause some very minor conflicts with Lucas's currently outstanding work on the HDA version of cs35l41. Whilst things will still build, this patch adds a test key function his code will now have to call. If his patches are getting merged first I will respin this series to update his code, he is currently on holiday until the 12th of Jan, so if we want to wait for another spin of those patches I can work with him to update them at that time. Or alternatively we could just merge them all and I will do a quick fixup patch at the end, since there is no build breakage.

[PATCH] ALSA: hda/realtek: Add quirk for Legion Y9000X 2020
by Baole Fang 05 Jan '22

05 Jan '22

Legion Y9000X 2020 has a speaker, but the speaker doesn't work. This can be fixed by applying alc285_fixup_ideapad_s740_coef to fix the speaker's coefficients. Besides, to support the transition between the speaker and the headphone, alc287_fixup_legion_15imhg05_speakers needs to be run.
