Subject: [BUG] snd_hda_intel runtime power management unsupported on MSI MPG Z390 GAMING PLUS with Realtek codec (kernel 6.8.0) causing excessive audio power draw
by Thomas van Houten 05 Aug '25

05 Aug '25

Dear Linux kernel and ALSA developers, I am reporting an issue related to runtime power management support for the onboard Realtek audio codec on my desktop motherboard, which results in continuously high audio hardware power usage and increased idle system power draw. *System Information:* * Kernel: 6.8.0-64-generic x86_64 * Distribution: Linux Mint 21.3 Virginia * Motherboard: MSI MPG Z390 GAMING PLUS (MS-7B51) * CPU: Intel Core i5-9400F * Audio Driver: snd_hda_intel * Audio Codec: Realtek (likely ALC1220 or similar) *Issue Summary:* The onboard Realtek audio codec does not enter runtime power management low-power states, causing it to remain at 100% power usage even when idle. This significantly contributes to my system's high idle power consumption (~160W total), despite low CPU and GPU draw. *Detailed Diagnostics:* 1. *PCI Audio Devices:* text |00:1f.3 Audio device [0403]: Intel Corporation Cannon Lake PCH cAVS [8086:a348] (rev 10) 03:00.1 Audio device [0403]: Advanced Micro Devices, Inc. [AMD/ATI] Navi 31 HDMI/DP Audio [1002:ab30] 07:00.1 Audio device [0403]: Advanced Micro Devices, Inc. [AMD/ATI] Navi 21/23 HDMI/DP Audio Controller [1002:ab28] | 2. *Kernel Messages related to snd_hda_intel or audio:* No logs found via|dmesg | grep -i snd_hda_intel|or|dmesg | grep -i audio|. 3. *Power management sysfs settings:* text |cat /sys/module/snd_hda_intel/parameters/power_save 10 cat /sys/class/sound/hwC*/power/runtime_status unsupported unsupported unsupported cat /sys/class/sound/hwC*/power/control auto auto auto | The|runtime_status|reports "unsupported", indicating no runtime PM support is available for these audio devices. 4. *PulseAudio and user-space processes inspection:* Stopped PulseAudio and all audio clients, with no change in power usage or device ownership of audio controls, confirming this is not caused by user-space audio applications. 5. *Powertop Reports:* text |100.0% Device Audio codec hwC2D0: Realtek | Consistently 100% usage from the Realtek audio codec, confirmed by powertop. 6. *Driver parameter set:* |snd_hda_intel|module|power_save|parameter successfully set to 10 seconds (value 10), but no effective power saving observed. *Impact:* The lack of runtime power management support for this audio codec causes continuous high power draw, increasing system idle power consumption significantly, reducing energy efficiency. *Request:* Please investigate whether this is a driver limitation, missing firmware quirk, or configuration issue with|snd_hda_intel|on the MSI MPG Z390 GAMING PLUS motherboard's Realtek codec. Guidance, workarounds, or patches to enable runtime power management would be appreciated. *Additional notes:* * Tested power management settings according to current best practices. * BIOS is up to date as of the latest MSI release. * System behavior consistent on Live USB of the same Linux Mint version—problem not due to local configuration. Thank you for your attention to this matter. I’m happy to provide additional logs or assist with testing patches. Best regards, Thomas van Houten

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
