ATI IXP - external amplifier option

[Pietro_S]

I have ATI IXP sound chip in ASUS (A6R) notebook.
When I try osstest I doesn't hear any sound, but after
plug in headphones or external speakers it's ok.

When I had linux with alsa on this machine, alsa had option
"External amplifier" by default ON, until it was turned off no sound
at all. How could I set this option in oss?

If you want any info, just tell I will post it.
Thanks in advance.

Look at ac97_amplifier in /usr/lib/oss/conf/osscore.conf and set it to 1.

Now reinstall the drivers by running ossdetect (make sure you're logged in as root on a *CONSOLE SESSION*).

Look at ac97_amplifier in /usr/lib/oss/conf/osscore.conf and set it to 1.

ac97_amplifier wasn't in that config file (nor in other files in same directory).
When I add it there and run ossdetect (from console), it's same as before.

Can you plug in a pair of headphones to see if audio is perhaps coming out the headphone port?

Yes, headphones works, also line-out works too.
But speakers in notebook don't work.

This is output from ossmix:

Didn't help at all ...

Print the output from cat /dev/sndstat - I'd like to see what is the AC97 device detected by OSS.
