[PATCH] ALSA: hda/realtek: Fix speaker pop on Star Labs StarFighter
From: Sean Rhodes
Date: Tue Feb 17 2026 - 06:53:41 EST
On Star Labs StarFighter (Realtek ALC233/235), the internal speakers can
emit an audible pop when entering or leaving runtime suspend.
Mute the speaker output paths via snd_hda_gen_shutup_speakers() in the
Realtek shutup callback before the codec is powered down.
This is enough to avoid the pop without special EAPD handling.
Test results:
- runtime PM pop fixed
- still reaches D3 (PCI 0000:00:1f.3 power_state=D3hot)
- does not address pops on cold boot (G3 exit) or around display manager
start/shutdown
journalctl -k (boot):
- snd_hda_codec_alc269 hdaudioC0D0: ALC233: picked fixup for PCI SSID
7017:2014
- snd_hda_codec_alc269 hdaudioC0D0: autoconfig for ALC233: line_outs=1
(0x1b/0x0/0x0/0x0/0x0) type:speaker
