[alsa-devel] unable to get alsa configured on Acer Aspire 1640Z
Hi,
I hope this is the right place to report this.
Computer: laptop Acer Aspire 1640Z
distro: Debian etch kernel: 2.6.17
lspci 00:1b.0 Audio device: Intel Corporation 82801FB/FBM/FR/FW/FRW (ICH6 Family) High Definition Audio Controller (rev 04)
lspci -nv 00:1b.0 0403: 8086:2668 (rev 04) Subsystem: 1025:009e Flags: bus master, fast devsel, latency 0, IRQ 177 Memory at d000c000 (64-bit, non-prefetchable) [size=16K] Capabilities: [50] Power Management version 2 Capabilities: [60] Message Signalled Interrupts: Mask- 64bit+ Queue=0/0 Enable- Capabilities: [70] Express Unknown type IRQ 0 Capabilities: [100] Virtual Channel Capabilities: [130] Unknown (5)
I've tried model=acer and acer-aspire to no avail.
I notice in dmesg after trying 'modprobe snd-hda-intel model=acer' this: hda_codec: Unknown model for ALC882, trying auto-probe from BIOS...
but alsamixer shows: Card: HDA Intel Chip: Realtek ALC883 at the top.
There seems to be uncertainty about which model number, 882 or 883. I wonder if this is the source of the difficulty.

Your kernel is 2.6.17. Its alsa driver is too older. It didn't provide patch_alc883 for ALC883 codec, but used the patch_alc882 for it. AND there is no "model acer" in it.
I suggest that you try latest alsa driver. Does model=acer or acer-aspire work?
I wonder if this is the source of the difficulty.

I have tried with the latest kernel in debian etch (2.6.18) This gives same error but with correct model number, ie hda_codec: Unknown model for ALC883, trying auto-probe from BIOS... when trying to load either model=acer or acer-aspire
It looks as though I have to wait to try kernel 2.6.24 as in debian unstable. When I have a fast internet connection one day, I shall try this. It is not practical or affordable to upgrade over GPRS.
Thankyou for the suggestion.

You can build alsa-driver modules externally. It's more standard procedure for debugging sound problems. Just configure and install as usual. See alsa-driver/INSTALL for details.
In your case, maybe better to try alsa-driver daily snapshot tarball than 1.0.16. See alsa-driver.project web page.

Oh, thanks. Sounds intimidating, but I'll see if I can manage that.
ll it matter if I do it with the 2.6.17 rather than 2.6.18 kernel, as the .18 flavour breaks ACPI on my box?
