[alsa-devel] ALSA does not detect the built-in microphone on HP EliteBook 850 G6
by lazarenkovegor 10 Jan '20

Hello! ALSA does not detect the built-in microphone on HP EliteBook 850 G6 with Ubuntu 19.10 Kenrel 5.3.0-27-generic I tried to specify the following "options snd-hda-intel model" in /etc/modprobe.d/alsa-base.conf : - *laptop-amic*,* laptop-dmic* - a recording device has appeared but it does not work. LED of MicMute on hardware button is always ON - *auto*, *3stack*,* hp-gpio4*,* hp-gpio-led*, *hp-dock-pins*, *hp-dock-gpio-mic*, *hp-9480m*, *alc280-hp-headset*, *alc221-hp-mic*, *hp-rp5800 *- there is no audio recorder in the system. LED of MicMute on hardware button is always ON - *hp-gpio2-hotkey *- there is no audio recorder in the system. LED of MicMute on hardware button is always OFF Can you help set up ALSA to work with the specified laptop? If necessary, I can compile and install the necessary patches and send work logs.

[alsa-devel] Applied "ASoC: max98090: Drop incorrectly applied duplicate commit" to the asoc tree
by Mark Brown 10 Jan '20

10 Jan '20

The patch ASoC: max98090: Drop incorrectly applied duplicate commit has been applied to the asoc tree at https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git All being well this means that it will be integrated into the linux-next tree (usually sometime in the next 24 hours) and sent to Linus during the next merge window (or sooner if it is a bug fix), however if problems are discovered then the patch may be dropped or reverted. You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed. If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced. Please add any relevant lists and maintainers to the CCs when replying to this mail. Thanks, Mark >From a84188eced6109983af54f9435a26d21eac3f8cc Mon Sep 17 00:00:00 2001 From: Mark Brown <broonie(a)kernel.org> Date: Fri, 10 Jan 2020 13:24:02 +0000 Subject: [PATCH] ASoC: max98090: Drop incorrectly applied duplicate commit This reverts commit 4e93c1294f4b051 (ASoC: max98090: fix incorrect helper in max98090_dapm_put_enum_double()) which was misapplied.

[alsa-devel] [PATCH] ASoC: stm32: dfsdm: fix 16 bits record
by Olivier Moysan 10 Jan '20

10 Jan '20

In stm32_afsdm_pcm_cb function, the transfer size is provided in bytes. However, samples are copied as 16 bits words from iio buffer. Divide by two the transfer size, to copy the right number of samples.

[alsa-devel] [PATCH 1/2] ASoC: max98090: fix incorrect helper in max98090_dapm_put_enum_double()
by Marek Szyprowski 10 Jan '20

10 Jan '20

Commit 62d5ae4cafb7 ("ASoC: max98090: save and restore SHDN when changing sensitive registers") extended the code for handling "LTENL Mux", "LTENR Mux", "LBENL Mux" and "LBENR Mux" controls by adding a custom max98090_dapm_put_enum_double() function to them. However that function used incorrect helper to get its component object. Fix this by using the proper snd_soc_dapm_* helper. This fixes the following NULL pointer exception observed on Exynos4412-based Odroid U3 board: 8<--- cut here --- Unable to handle kernel NULL pointer dereference at virtual address 000000b0 pgd = (ptrval) [000000b0] *pgd=00000000 Internal error: Oops: 5 [#1] PREEMPT SMP ARM Modules linked in: CPU: 0 PID: 1104 Comm: alsactl Not tainted 5.5.0-rc5-next-20200107 #166 Hardware name: SAMSUNG EXYNOS (Flattened Device Tree) PC is at __mutex_lock+0x54/0xb18 LR is at ___might_sleep+0x3c/0x2e0 ...

[alsa-devel] Bug report for changes in ucm2 with chtrt5645 card on Lenovo Miix 320
by Tim Schumacher 10 Jan '20

10 Jan '20

Hi alsa devs, I'm on Arch Linux on a rather uncommon laptop (Lenovo Miix 320) and my sound stopped working on the upgrade from alsa-lib 1.1.9 to 1.2.1. wabbits on IRC helped me track down the problem to a change in the /usr/share/alsa/ucm (now /usr/share/alsa/ucm2) files. It seems like /usr/share/alsa/ucm2/chtrt5645/HiFi-dmic2.conf and a symlink at /usr/share/alsa/ucm2/chtrt5645/LENOVO-80XF-LenovoMIIX320_10ICR-LNVNB161216.conf were specifically added for this laptop but in the contrary they break the sound for me. After the upgrade to alsa-lib 1.2.1 the sound is not working. The commands play no sound: pasuspender -- speaker-test --nloops=1 --channels=2 --test=wav --device=hw:0,0 pasuspender -- speaker-test --nloops=1 --channels=2 --test=wav --device=hw:0,1 And this is the alsa-info.sh output http://alsa-project.org/db/?f=f883910a5c5101b4b1ea4202d1fe84ccd139f796 After deleting the /usr/share/alsa/ucm2/chtrt5645/LENOVO-80XF-LenovoMIIX320_10ICR-LNVNB161216.conf symlink both commands from above play sound and this is the alsa-info.sh output http://alsa-project.org/db/?f=e759eb9118a191b6c3b8c021fed58abc9cf95076 Thanks. - Tim
