Hi Mike.
At least we know what the codec is now.
As both your threads have been running for a while, perhaps we could go back,
and get some basic details.
Which machine do you have? Make/model. PC, or laptop.
Sound was working on your i686 install, and I presume that was Lenny, but when
you installed x86_64/AMD64 version of Lenny, sound no longer worked. Was that
a totally fresh install of the 64 bit version of Lenny?
Personally I'd go back to the i686 version of Lenny, where the sound was
working. I've seen conflicting reports of the benefits of using a 64 bit OS.
Only my opinion, and of course it's your choice.
Anyway. Back to the ALC885 codec. There are a bunch of model options for this
codec with the 1.0.16 alsa driver, as below. I see the same model options for
the 1.0.18a alsa driver, but bear in mind that the alsa developers are
continually applying patches to the alsa driver, so maybe upgrading to the
latest alsa driver is an option. The link for the latest is also below.
ALC882/885
3stack-dig 3-jack with SPDIF I/O
6stack-dig 6-jack digital with SPDIF I/O
arima Arima W820Di1
targa Targa T8, MSI-1049 T8
asus-a7j ASUS A7J
asus-a7m ASUS A7M
macpro MacPro support
mbp3 Macbook Pro rev3
imac24 iMac 24'' with jack detection
w2jc ASUS W2JC
auto auto-config reading BIOS (default)
Latest alsa driver obtainable from link below, and if you want the latest
nightly snapshot of the driver, that's the 2nd link.
http://alsa-project.org/main/index.php/Main_Page
http://ftp.kernel.org/pub/linux/kernel/people/tiwai/snapshot/
If you're not sure on how to upgrade the alsa driver, just ask.
All the best.
Nigel.
