HP OMEN Transcend 14 (board 8C58, Meteor Lake) – SoundWire speakers not configured (missing UCM profile)
alsa-project/alsa-ucm-conf issue #661 was opened from Farnaz03:
### **Hardware**
* Model: HP OMEN Transcend Gaming Laptop 14-fb0xxx * Board ID: **8C58** * CPU: Intel Meteor Lake-P * Audio: Intel SOF + SoundWire * Codec(s): rt711-sdca (headset), rt1316 (speaker amp) * OS: Ubuntu 24.04 LTS
### **Kernels tested**
* 6.8.0-88-generic * 6.8.0-90-generic * 6.14.0-1008-oem * 6.14.0-1014-oem
---
### **Description**
Internal speakers produce no sound on Linux. SOF firmware and SoundWire devices are detected successfully, and a Speaker PCM exists, but no UCM profile configures or enables the speaker path.
Audio reportedly worked earlier (May–July 2025) and stopped after an update around August 2025.
---
### **DMI / board identification**
``` sys_vendor : HP product_name : OMEN Transcend Gaming Laptop 14-fb0xxx board_name : 8C58 board_vendor : HP ```
---
### **SOF topology in use**
``` intel/sof-ace-tplg/sof-mtl-rt711-l0-rt1316-l3-2ch.tplg ```
---
### **aplay -l**
``` card 1: sofsoundwire [sof-soundwire], device 0: Jack Out card 1: sofsoundwire [sof-soundwire], device 2: Speaker card 1: sofsoundwire [sof-soundwire], device 31: Deepbuffer Jack Out ... ```
---
### **ALSA direct tests (PipeWire bypassed)**
``` aplay -D hw:1,2 /usr/share/sounds/alsa/Front_Center.wav aplay -D hw:1,0 /usr/share/sounds/alsa/Front_Center.wav aplay -D hw:1,31 /usr/share/sounds/alsa/Front_Center.wav ```
All fail with:
``` aplay: set_params: Channels count non available ```
---
### **UCM status**
``` /usr/share/alsa/ucm2/sof-soundwire/ -> empty (no profiles) ```
---
### **Expected result**
Internal speakers work via ALSA / PipeWire.
### **Actual result**
Speaker PCM exists but is unusable due to missing UCM configuration.
### **Request**
Add a UCM profile for HP OMEN Transcend 14 (board 8C58) under `sof-soundwire`, enabling the speaker path for the existing SOF topology.
### Optional notes / suggestions
This platform uses SOF SoundWire with rt1316 speaker amp and rt711 headset codec, and the loaded topology already supports a 2-channel speaker path:
sof-mtl-rt711-l0-rt1316-l3-2ch.tplg
It may be possible to adapt or clone an existing HP SoundWire UCM profile for Meteor Lake platforms using rt1316 (if available), matching DMI board ID `HP / 8C58`.
I am happy to test patches or provide additional logs if needed.
