Public bug reported:
Hardware: Dell XPS 13 9350, Realtek ALC3246 codec, subsystem ID 0x10280704
Distro: Linux Mint 22.3 (Zena), based on Ubuntu 24.04 (noble)
Kernel: 6.17.0-35-generic (regression believed introduced upgrading from the
6.14 series; internal speaker worked prior to this upgrade)
Symptom: Internal laptop speaker produces no audio — only a faint click per
channel on speaker-test. All other outputs work normally: 3.5mm headphone jack,
USB-C headphones, and Bluetooth headphones.
Verified working / ruled out:
aplay -l detects the card (card 0: PCH [HDA Intel PCH], ALC3246 Analog)
PipeWire running and healthy; wpctl status shows correct default sink (Built-in
Audio Analog Stereo, vol 0.88), not muted
All ALSA mixer channels unmuted and raised: Master, Speaker (90%, [on]), PCM
amixer -c 0 get 'Auto-Mute Mode' → Disabled
speaker-test -D hw:0,0 -c2 -twav → click only on internal speaker; real tones
on headphone jack (same codec, different pin)
Note: Possibly related to LP bug #2131090 (audio regression on 6.14 →
6.17 upgrade, different hardware).
** Affects: linux (Ubuntu)
Importance: Undecided
Status: New
