Any ideas? It's because BIOS on your machine doesn't set the whole audio pins correctly. Try to put the file attached below as /lib/firmware/alsa/alc260-sony, then pass a module option patch=alsa/alc260-sony to snd-hda-intel driver. This will override the pin configs and sets three pins. The values are taken from other Sony VAIO with ALC260, so it might not cover all I/Os on yours or might be wrong. Takashi
