ALC4082: S/PDIF volume redirecting to headphone volume - asus rog crosshair x670e hero

alsa-project/alsa-ucm-conf issue #598 was edited from LuanVSO: hi, i had a problem where opening the kde plasma volume applet would make the volume on my headphone jump to the maximum. after muting the "PCM 2" channel on alsamixer i notice that the volume on the headphone would go muted instead. so i edited the ALC4080-HiFi.conf file and remove every mention of S/PDIF and rebooted my machine. after the change the problem didn't happen anymore. what do you need to fix the mapping problem? i think this happens because the "PCM 2" volume controls is redirecting to headphone output, but it doenst have a slider, so it is either max or muted: <img width="1259" height="967" alt="Image" src="https://github.com/user-attachments/assets/3b266bb7-7e1c-4a7a-b448-affabf06…" /> (also the S/PDIF aways appeared as connected even though i did not have anything connected to it, don't know if it is expected) [alsa-info.txt](https://github.com/user-attachments/files/21583734/alsa-info… <details> <summary>edited ALC4080-HiFi.conf</summary> ``` Define { SpeakerMixer "PCM" SpeakerMindex "0" SpeakerJack "Speaker -

Regression: Microphone broken on Intel Ice Lake with alsa-ucm-conf 1.2.10-150600.3.5.1 (openSUSE Leap 15.6)
by Pablo Scatizza 04 Aug '25

04 Aug '25

Dear ALSA developers, I would like to report a regression affecting the microphone on my laptop using Intel's Ice Lake-LP audio controller with the `sof-hda-dsp` driver. After upgrading `alsa-ucm-conf` to version 1.2.10-150600.3.5.1 (as distributed in openSUSE Leap 15.6), the internal microphone stops working. No capture is possible via `arecord` or any application. The device still shows up in `arecord -l`, but it does not receive audio input. Rolling back to the previous version (1.2.10-150600.1.2) using: sudo zypper install --oldpackage alsa-ucm-conf-1.2.10-150600.1.2.noarch restores full microphone functionality. **System information:** - Distribution: openSUSE Leap 15.6 - Kernel: 6.4.0-150600.23.53-default - Audio device: Intel Corporation Ice Lake-LP Smart Sound Technology Audio Controller (rev 30) - ALSA driver: sof-hda-dsp **Working `arecord -l` output with the old version:** card 0: sofhdadsp [sof-hda-dsp], device 0: HDA Analog ( *) [] card 0: sofhdadsp [sof-hda-dsp], device 6: DMIC (*) [] card 0: sofhdadsp [sof-hda-dsp], device 7: DMIC16kHz (*) [] Let me know if I can provide logs, diffs between UCM files, or further testing. I'd be happy to help. Best regards, Pablo Scatizza Neuquén, Argentina

[PATCH 1/2] ALSA: hda/realtek: Accelerate the front MIC charging and discharging of the 897 codec
by wangdich9700＠163.com 04 Aug '25

04 Aug '25

From: wangdicheng <wangdicheng(a)kylinos.cn> The front MIC capacitance of the Inspur board is too large, resulting in a longer charging and discharging time required, which in turn prevents recording for 5 seconds before startup. Therefore, software is used to increase the delay by 2 seconds to avoid this issue.

[PATCH REQUEST] ALSA: hda/tas2781: Add support for ASUS VivoBook 16 Flip TP3607SA
by Ludd ite 02 Aug '25

02 Aug '25

Summary ======= The ASUS VivoBook 16 Flip TP3607SA laptop contains TI TAS2781 smart amplifiers but they are not supported by the current snd_hda_scodec_tas2781_i2c driver. The driver fails to initialize with "Platform not supported" error, preventing internal speakers from working. Hardware Information ==================== Laptop Model: ASUS VivoBook 16 Flip TP3607SA_TP3607SA BIOS Version: 1.0 PCI Audio Device: Intel Lunar Lake-M HD Audio Controller [8086:a828] (rev 10) Subsystem Vendor: 0x1043 (ASUS) Subsystem Device: 0x3e30 Audio Codec: Realtek ALC294 (HDA:10ec0294,10433e30,00100004) Smart Amplifier: TI TAS2781 on I2C bus (ACPI ID: TIAS2781:00) System Information ================== OS: Ubuntu 25.04 (development) Kernel: 6.14.0-1007-realtime Audio System: PipeWire with SOF (Sound Open Firmware) SOF Firmware: intel/sof-ipc4/lnl/sof-lnl.ri (version 2.12.0.1) Topology: intel/sof-ipc4-tplg/sof-hda-generic-2ch.tplg Current Behavior ================ 1. Audio Detection: SOF firmware loads successfully and creates speaker sink in PipeWire 2. Audio Pipeline: Complete audio pipeline works (volume controls, routing, mixing) 3. TAS2781 Driver: Fails to bind with the following errors: tas2781-hda i2c-TIAS2781:00: Failed to get Speaker id. tas2781-hda i2c-TIAS2781:00: read acpi error, ret: -2 tas2781-hda i2c-TIAS2781:00: error -ENOENT: Platform not supported tas2781-hda i2c-TIAS2781:00: probe with driver tas2781-hda failed with error -2 4. Result: No sound from internal speakers (Bluetooth and HDMI audio work fine) Technical Analysis ================== - I2C Device Present: i2c-TIAS2781:00 device exists and is detected - ACPI Information: Device has ACPI ID TIAS2781: but driver cannot read required configuration - Volume Control: Audio shows active volume bars in pavucontrol, indicating software pipeline works - Driver Status: TAS2781 driver loads but doesn't bind to the device due to platform whitelist Evidence of TAS2781 Hardware ============================= I2C device exists: $ ls /sys/bus/i2c/devices/i2c-TIAS2781:00/ firmware_node modalias name power subsystem Device modalias: $ cat /sys/bus/i2c/devices/i2c-TIAS2781:00/modalias acpi:TIAS2781: PipeWire detects speaker sink: $ pactl list sinks short | grep Speaker 60 alsa_output.pci-0000_00_1f.3-platform-skl_hda_dsp_generic.HiFi__Speaker__sink Expected Behavior ================= The TAS2781 driver should recognize the ASUS VivoBook 16 Flip TP3607SA (subsystem ID 1043:3e30) as a supported platform and successfully initialize the smart amplifiers, enabling internal speaker audio output. Workarounds Attempted ===================== 1. Manual I2C device creation: Created tas2781 devices at addresses 0x38-0x3b, but they fail with communication timeouts (error -121) 2. Driver parameters: Tried various modprobe options, but the driver doesn't expose platform override parameters 3. GPIO manipulation: Attempted to enable GPIO pins that might control amplifier power, without success 4. Kernel versions: Tested multiple 6.14.x kernels including recent versions with November 26, 2024 ASUS TAS2781 improvements Request ======= Please add support for ASUS VivoBook 16 Flip TP3607SA (subsystem ID 1043:3e30) to the TAS2781 driver's supported platform list. This appears to be a matter of adding the device ID to the driver's whitelist and possibly providing the appropriate ACPI configuration parsing. Additional Notes ================ - This is a recent laptop model (2024) with Intel Lunar Lake platform - Other ASUS laptops may have similar TAS2781 configurations - The November 26, 2024 commit "ALSA: hda/tas2781: Add speaker id check for ASUS projects" suggests ongoing work on ASUS TAS2781 support - Hardware detection is working perfectly through SOF firmware Contact Information =================== Available for testing patches or providing additional debugging information. Attachments =========== - Full dmesg output available upon request - ACPI tables dump available if needed - Detailed hardware information via sudo lshw available

retire_capture_urb: Corrected urb data len
by Sean Anderson 01 Aug '25

01 Aug '25

Hi all, I have a "FiiO DigiHug USB Audio" sound card (1852:7022) [3]. I have had no problems with the audio, but I did notice a large number of message like retire_capture_urb: 4992 callbacks suppressed in my dmesg [1]. This is caused by the "Corrected urb data len." warning. The patch adding this warning [2] makes it seem like this warning should be an uncommon occurance. However, based on the number of suppressed callbacks, this seems to be happening at a rate of around 500 Hz. Is this buggy hardware? Or is this a bug in the driver? Does there need to be a quirk? Or perhaps the warning above should be a debug instead? I'm using 5.15.0-46-generic. I know, I know; this is a vendor kernel. However, I went through the commits for sound/usb/pcm.c and didn't see any major differences. I also previously saw this issue on 5.4, so this probably isn't a regression. --Sean [1] I would have liked to post the actual message, but I was unable to figure out how to disable ratelimiting. I tried setting /proc/sys/kernel/printk_ratelimit to 0, /proc/sys/kernel/printk_ratelimit_burst to 5000, and /proc/sys/kernel/printk to 8. However, nothing seemed to have any effect (except that the callbacks suppressed messages were disabled). I find this very strange, given that the callbacks suppressed message uses KERN_WARN, and so does dev_warn_ratelimited.
