My cheap hard drive crashed on my Myth front-end machine.
I had to reinstall Mandrake, so I thought I would try 9.1 .

The sound came out with crackle and pop so I tried upgrading to the Latest ALSA.
This did not solve the problem till I found this info.

This is most probably due to the fact that you’re using the wrong Sampling speed. It avered to work correctly when using the alsa-Drivers 0.9.4 - but you’ll have to recompile these. Under Mandrake however - these will only compile if you deactivate the verbose-printk stuff. In the Alsa-Driver directory, compile it using:

./configure –disable-verbose-printk && make && make install

or you’ll get unresolved dependencies. Once this is done, make sure the alsa drivers are loaded using dxs_support=3. In the /etc/modules.conf - this will look like:

# Sound Stuff
above snd-via82xx snd-pcm-oss
alias sound-slot-0 snd-via82xx
options snd-via82xx dxs_support=3

And it should work

I have had no luck with the video yet! So I have gone back to 9.0 so I can use the slim driver.
