GIven the recent changes in gnome land (pulseaudio), I'd like to be able to get alsa support for my hardware fixed up. My biggest annoyance right now is that when I plug headphones in, it doesn't mute the speakers. Another issue I have is that I'd like to have support for audio out on HDMI (which is supported by Vista). On with the show.
Try the later version of alsa-driver or kernel, and pass model=auto. As default model=acer is chosen for ALC883 with Acer vendor SSID, and it's known that it doesn't match with the recent Acer laptops at all. The BIOS auto-parsing mode would work better recently.
I still get dmesg errors (audio does play though):
[229513.339812] hda-intel: Invalid position buffer, using LPIB read method instead. [229513.436583] hda-intel: IRQ timing workaround is activated for card #0. Suggest a bigger bdl_pos_adj.
These are no errors. You can ignore for now. Which alsa-driver are you using now? At best, try the latest alsa-driver snapshot from ftp://ftp.kernel.org/pub/linux/kernel/people/tiwai/snapshot/alsa-driver-snapshot.tar.gz or the sound git tree at git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound-2.6.git
The Center mixer control now controls my left laptop speaker and the LFE mixer control controls the right speaker. The Surround control that used to control the laptop speakers now does nothing.
Attempting to MUTE the LFE channel, the audio skipped a bit and I got:
[229698.556044] hda_intel: azx_get_response timeout, switching to polling mode: last cmd=0x10db0001 [229699.561017] hda_intel: azx_get_response timeout, switching to single_cmd mode: last cmd=0x10db0001
My system just hung (likely due to wireless drivers) and I rebooted and with model=auto again, the mixer controls are different. There is no LFE or Center controls, but there is an added Headphone volume control (which does nothing). Front controls the headphone volume, nothing controls the speaker volume.
I've been unable to hear digital output (mplayer -ao alsa:device=iec958).
The device is likely not "iec958" but "hdmi".
My laptop has an internal microphone, two internal speakers, a headphone jack, a mic in jack, a line in jack, and digital audio out via hdmi.
And alsa-info output? Use model=auto from now on. The default model (acer) doesn't work obviously for your laptop.
