I just had the same issue but on Acer Predator PH315-54 alsa-info.sh output: http://alsa- project.org/db/?f=66787dea0436de3059aac928371c61646ebad51b
Jaroslav, I sent a patch for you and alsa-devel, but I think it did not arrive as I am not a member of the list. I just applied the same quirk and recompiled, resulting in a working headset microphone. Thank you a lot for all the information/guidance in this issue. diff --git a/sound/pci/hda/patch_realtek.c b/sound/pci/hda/patch_realtek.c index 6fab7c8fc19a..5b628fd3351d 100644 --- a/sound/pci/hda/patch_realtek.c +++ b/sound/pci/hda/patch_realtek.c @@ -9202,6 +9202,7 @@ static const struct snd_pci_quirk alc269_fixup_tbl[] = { SND_PCI_QUIRK(0x1025, 0x142b, "Acer Swift SF314-42", ALC255_FIXUP_ACER_MIC_NO_PRESENCE), SND_PCI_QUIRK(0x1025, 0x1430, "Acer TravelMate B311R-31", ALC256_FIXUP_ACER_MIC_NO_PRESENCE), SND_PCI_QUIRK(0x1025, 0x1466, "Acer Aspire A515-56", ALC255_FIXUP_ACER_HEADPHONE_AND_MIC), + SND_PCI_QUIRK(0x1025, 0x1534, "Acer Predator PH315-54", ALC255_FIXUP_ACER_MIC_NO_PRESENCE), SND_PCI_QUIRK(0x1028, 0x0470, "Dell M101z", ALC269_FIXUP_DELL_M101Z), SND_PCI_QUIRK(0x1028, 0x053c, "Dell Latitude E5430", ALC292_FIXUP_DELL_E7X), SND_PCI_QUIRK(0x1028, 0x054b, "Dell XPS one 2710", ALC275_FIXUP_DELL_XPS), -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1912052 Title: [Acer Spin 5 - SP513-54N] External headset microphone not working on Ubuntu 21.04 (not even wired, cable headset) Status in Linux: Confirmed Status in linux package in Ubuntu: Fix Released Status in linux source package in Bionic: New Status in linux source package in Focal: Fix Released Status in linux source package in Hirsute: Won't Fix Status in linux source package in Impish: Fix Released Status in linux source package in Jammy: Fix Released Bug description: Recently, external microphone has stopped working while using classic wired audio combo jack headset.
