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.
