[PATCH RESEND] ASoC: rt5650: Eliminate the high frequency glitch
by derek.fang＠realtek.com 21 Jul '25

21 Jul '25

From: Derek Fang <derek.fang(a)realtek.com> The glitch was detected in the high frequency of the HP playback. This patch adjusts the DAC dither setting to avoid this situation for almost all cases.

Internal Microphone not working

alsa-project/alsa-lib issue #464 was opened from crashthepose: After updating my computer my internal microphone is not working. Originally when I went to my Audio settings it would say under Input "headset unplugged". I was able to go into the HDAjackretask interface and override one of the pins where now the internal microphone is showing on the input list but now I only hear static noise.

speaker-test 1.2.13 dose not produce 20kHz sine wav
by GitHub issues - opened 17 Jul '25

17 Jul '25

alsa-project/alsa-utils issue #304 was opened from gharig: Hello Alsa-Dev, I hope that I’m writing to the proper place to report a problem, please advise if not… I’m not able to produce 20kHz sine wav with speaker-test 1.2.13 Running on Tinycore 16.0 . Below is what I submitted to Tinycore Team, and they suggested that I contact you with my findings. The hardware I’m using is Winsystems E3825 dual-core, 1.33GHz SATA 2.0 channel mSATA socket (shared with miniPCIe) 2 GB of Soldered Down DDR3 [https://winsystems.com/product/ppm-c407/](url) Tinycore Team; My problem today is that speaker-test does not produce a 20kHz sine wave on Tinycore 16.0 to the line out. speaker-test does produce something just not a 20kHz sine wave. Code: ` speaker-test -t sine -f 20000 -X -l 0` However, using the exact same hardware running Ubuntu 20.24 or 22.04 the following code works and a 20kHz sine wave is produced. The difference being that the alsa versions are different between the 3 Operating Systems. Tinycore 16.0 Alsa version is 1.2.13 - failure Ubuntu 20.04 Alsa version is 1.2.2 - success Ubuntu 22.04 Alsa version is 1.2.6 - success Through my testing, starting at 8000 Hz, and incrementing by 1000 Hz, speaker-test does produce a sine wave, until I went over 15000 Hz then no more sine wave. :) :) Code: ``` speaker-test -t sine -f 8000 -X -l 0 speaker-test -t sine -f 15000 -X -l 0 ``` :( Code: ` speaker-test -t sine -f 16000 -X -l 0` The work around for the time being is to configure speaker-test to play a 20kHz wav file, this dose work and produces a beautiful sine wav :) Code: ` speaker-test -t wav -f /opt/20kHz.wav -l 0` Now for the people who will say why on earth do you want to produce a sound that no one can hear, and my reply is "Exactly". I send the 20kHz sine wav across the audio line as a way to supervise that the audio line is fully functioning. The second the 20kHz tone stops we are notified and send someone out to fix the problem, whether it be hardware or someone accidentality cuts the wire, we want to know. Basically the 20 kHz sine wave does not interferer with paging in the system. My first thoughts on why the 20 kHz sine is not produced, is because of missing driver. But I made sure that every sound driver that was loaded on Ubuntu was loaded on Tinycore. Code: ` sudo modprobe snd_seq_midi snd_seq_midi_event snd_intel_dspcfg` I also loaded AlsaPlugins.tcz just incase, but that did not make a difference. Code: ` tceload -i alsa-plugins.tcz` The last thing I tried after was to set the format sample -F parameter to 96000 Code: `speaker-test -t sine -f 20000 -X -l 0 -F 96000` At first when I did this I thought I was so smart. A sine wave appeared, however I did not have a speaker hooked up, but when the speaker got plugged in I heard a high pitched noise. So the parameter affected the output but not the desired output that I need. Another thought that pass through my mind is could this be a configuration setting during the build of alsa that need to be turned on. After all 15000 Hz does work. This is slightly related to a previous post linked below.

[alsa-devel] Applied "ASoC: tlv320aic32x4: Model CODEC_CLKIN in CCF" to the asoc tree
by Mark Brown 17 Jul '25

17 Jul '25

The patch ASoC: tlv320aic32x4: Model CODEC_CLKIN in CCF 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 fd2df3aeafa4b4cc468d58e147e0822967034b71 Mon Sep 17 00:00:00 2001 From: Annaliese McDermond <nh6z(a)nh6z.net> Date: Thu, 21 Mar 2019 17:58:46 -0700 Subject: [PATCH] ASoC: tlv320aic32x4: Model CODEC_CLKIN in CCF Model and manage codec clock input as a component in the Core Clock Framework. This should allow us to do some more complex clock management and power control. Also, some of the on-board chip clocks can be exposed to the outside, and this change will make those clocks easier to consume by other parts of the kernel.

[PATCH] ASoC: qcom: x1e80100: Support boards with two speakers
by Krzysztof Kozlowski 17 Jul '25

17 Jul '25

Some Qualcomm X1E laptops have only two speakers. Regardless whether this sound card driver is suitable for them (we could re-use one for some older SoC), we should set reasonable channel map depending on the number of channels, not always 4-speaker setup. This change is necessary for bringing audio support on Lenovo Thinkpad T14s with Qualcomm X1E78100 and only two speakers.

qcom-lpass: RX HPH Mode is set to a ULP mode which causes distortion
by GitHub issues - opened 17 Jul '25

17 Jul '25

alsa-project/alsa-ucm-conf issue #595 was opened from valpackett: The headphone enable sequence for all Qualcomm devices sets `CLS_H_ULP` mode: https://github.com/alsa-project/alsa-ucm-conf/blob/1b69ade9b6d7ee37a87c08b1… I was trying to figure out why I was getting horrendous distortion on the headphone jack of my Dell Latitude 7455 laptop above a certain relatively-quiet volume level. After lots of fiddling and searching (thanks, [XDA forum audio modders](https://xdaforums.com/t/mod-audio-biquads-utilizing-qualcomms-audi… from several years ago!) I figured it out. Changing that to `CLS_AB_HIFI` has completely fixed the distortion! Should the default be changed to a HIFI mode for everyone, i.e. right in that file? ping: @Srinivas-Kandagatla Issue URL : https://github.com/alsa-project/alsa-ucm-conf/issues/595 Repository URL: https://github.com/alsa-project/alsa-ucm-conf
