SUMMARY | 问题概要
Hardware:
Laptop: HP Envy x360
Codec: Realtek ALC245
Audio driver: sof-hda-dsp / HDA Intel PCH
Environment:
OS: Deepin 25.2.0 (latest)
PipeWire: 1.6.4-1deepin10
WirePlumber: 0.5.14-1deepin4
Kernel: (please add uname -r output)
Note: Speaker works fine when switched to Fedora or Windows.

No response
STEPS TO REPRODUCE | 复现步骤
What I tried:
Default SOF driver (sof-hda-dsp) → speaker silent.
Installed PipeWire stack (pipewire, pipewire-pulse, pipewire-alsa, wireplumber) → still no sound.
Restarted services (systemctl --user restart pipewire pipewire-pulse wireplumber) → no change.
Forced HDA driver with options snd-intel-dspcfg dsp_driver=1 → devices show up as ALC245 Analog, but speaker still silent.
Tried paplay, aplay -D hw:0,0 → playback silent or “Device busy”.
Checked sinks with pactl list short sinks → only analog-stereo appears, but no sound output.
Mixer (alsamixer) shows channels, unmuted, but no audio.
EXPECTED RESULT | 期望的结果
Speaker should output sound via ALC245 Analog.
PipeWire should expose sink correctly and playback should work.
OBSERVED RESULT | 观察到的结果
Speaker silent even when sink is set to analog-stereo.
aplay reports “Device or resource busy” when PipeWire stopped.
ADDITIONAL INFORMATION | 额外补充
Speaker works fine when switched to Fedora or Windows.
