(Aspire 9303) In 2.6.18 the audio worked fine, but now I've upgraded to 2.6.22 it has stopped working.=20 I note that there is a acer specific quirk mode in patch_realtek.c enabled for all acer devices introduced in the timeframe. Disabling the quirk so that the driver uses it auot mode makes playback work fine again. To be clear this pathc seems to work for me:- --- /usr/src/linux-source-2.6.22/sound/pci/hda/patch_realtek.c 2007-07-09 0= 0:32:17.000000000 +0100 +++ linux-source-2.6.22/sound/pci/hda/patch_realtek.c 2007-08-20 22:21:37= =2E000000000 +0100 @@ -6392,7 +6392,7 @@ SND_PCI_QUIRK(0x1462, 0x4319, "MSI", ALC883_TARGA_DIG), SND_PCI_QUIRK(0x1462, 0x4324, "MSI", ALC883_TARGA_DIG), SND_PCI_QUIRK(0x1462, 0xa422, "MSI", ALC883_TARGA_2ch_DIG), - SND_PCI_QUIRK(0x1025, 0, "Acer laptop", ALC883_ACER), +/* SND_PCI_QUIRK(0x1025, 0, "Acer laptop", ALC883_ACER) , */ SND_PCI_QUIRK(0x15d9, 0x8780, "Supermicro PDSBA", ALC883_3ST_6ch), SND_PCI_QUIRK(0x161f, 0x2054, "Medion laptop", ALC883_MEDION), SND_PCI_QUIRK(0x1071, 0x8258, "Evesham Voyaeger", ALC883_LAPTOP_EAP= D),=20 Unfortunately I think it's pretty clear it will break for others.
