What I tried: - Verified devices in `aplay -l` (ALC294 appears as HDA Intel PCH). - Set analog sink as default in PipeWire/PulseAudio. - Unmuted/raised volumes in alsamixer (Speaker/Master/Headphone). - Switched from SOF to legacy HDA driver (`options snd-intel-dspcfg dsp_driver=1`). - Tried model quirks: asus-zenbook, alc294-laptop, dell-headset-multi, lenovo-yoga, asus-nb-wmi. - Restarted services; tried OEM kernel. - hdajackretask overrides for likely pins (0x17, 0x14, 0x1a, 0x21) – no effect. - hda-verb EAPD/pin enables – no effect. - Firmware verb patches (alc294-sound-patch.fw) – no effect. Expectation: - Internal speakers and internal microphone should work out of the box. - It appears a DMI-based UCM/ALSA quirk for this exact ASUS model is missing. Request: - Please add a quirk/UCM profile for ASUS EXPERTBOOK B9403CVAR (Subsystem Id 0x10431e93) so that internal speakers and microphone are routed and functional.
