ALSA master volume mixed up with headphone for Intel 845G with AD1981A AC'97 codec

Description of problem:
I have a Compaq Evo D310vm with Intel 845G chipset and AD1981A AC'97
codec. When I change the master volume in alsamixer I get no sound,
but when I change headphone volume I get correct sound volume. That
was not happened before with kernel 2.4 and OSS.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. run alsamixer on computer with similar hardware configuration
2. check out headphone volume vs. master volume behaviour
The master volume does not affect the volume at all while headphone does
It should change master volume
any improvement with latest updates ?
I had an opportunity to test it with kernel 2.4 again and it turned out that I
was wrong. It happen with it too. Seems that it is all Compaq's fault. And now
we have upgraded our computers here at work so I can't test it anymore. Sorry
for not reporting this earlier.
