[PATCH v1] ASoC: SDCA: bug fix while parsing mipi-sdca-control-cn-list
by Niranjan H Y 10 Nov '25

10 Nov '25

"struct sdca_control" declares "values" field as integer array. But the memory allocated to it is of char array. This causes crash for sdca_parse_function API. This patch addresses the issue by allocating correct data size.

alsa-project/alsa-ucm-conf issue #639 was opened from nikola-maric-aula: I did a bisect and found that after https://github.com/alsa-project/alsa-ucm-conf/pull/628 my audio configuration wouldn't recognize the audio controller properly. Let me know what other details you want me to include. I'm on Zen kernel mostly, but have also tried LTS and mainline. Before: ```bash λ › wpctl status | grep -A15 'Audio$' Audio ├─ Devices: │ 46.

[REGRESSION?] No sound from internal speakers on Teclast T.BOLT with Realtek ALC256
by Marco Aurelio Osorio De León 08 Nov '25

Subject: [REGRESSION?] No sound from internal speakers on Teclast T.BOLT with Realtek ALC256 Hello everyone, I have a Teclast T.BOLT laptop with a Realtek ALC256 audio codec. The problem is that the sound from the internal speakers isn't working. The audio works perfectly through headphones, but when I disconnect them, there's no sound from the speakers. In the graphical interface (PulseAudio/PipeWire), the volume bar moves as if the sound were playing correctly, but there's no physical audio output. I've tried numerous solutions without success: - I checked `alsamixer` to ensure nothing is muted and that "Auto-Mute" is enabled. - - Tested multiple `model` parameters for `snd-hda-intel` in `/etc/modprobe.d/alsa-base.conf` and also as a kernel parameter in GRUB (dell-xps-13-9360, dell-headset-multi, lenovo-legion-15imhg05, alc255-dell1, etc.). - Tried reconfiguring the pins with `hdajackretask`, forcing pin 0x14 to "Internal Speaker (LFE)" and testing different configurations for pin 0x21. - Attempted several `hda-verb` commands to force the codec state, both with `SET_COEF_DATA` and `SET_PIN_WIDGET_CONTROL`, but without success. The hardware is working correctly, as the speakers function without problems on a Windows 11 installation on the same laptop. This appears to be a configuration issue with the generic Linux driver for this specific hardware. I've switched from the standard Ubuntu 25.10 kernel to Liquorix, but there's no change. Linux XXXXX 6.17.7-1-liquorix-amd64 #1 ZEN SMP PREEMPT_DYNAMIC liquorix 6.17-7ubuntu1~questing (2025 x86_64 GNU/Linux) I generated a full report using `alsa-info.sh`. The URL is: https://alsa-project.org/db/?f=96176a5abcc90780bbba4a67dac946be6b793c2c Any ideas on what else I could try, or if it might be a bug that requires a specific fix for this laptop? Thank you for your time and effort. Regards.
