I attached the alsa-info. This issue seems to be specific to the driver provided by Acer (with thx, equalizer etc.) Thanks for your help.

Thanks. Could you check whether the patch below works?

--- From: Takashi Iwai tiwai@suse.de Subject: [PATCH] ALSA: hda - Fix GPIO for Acer Aspire 3830TG

Acer Aspire 3830TG seems requiring GPIO bit 0 as the primary mute control. When a machine is booted after Windows 8, the GPIO pin is turned off and it results in the silent output.

This patch adds the manual fixup of GPIO bit 0 for this model.
