Hello all
after trying to set up the sound on the 6.1 RELEASE on a acer aspire
3100
notebook, I realise that the driver for the sound chip was the HDA
(high definition audio)
That notebook use a realtek version of the sound ship.
The code I get in the internet does not compile in the 6.1-RELEASE
it complains about some
missing entry points in the sound.ko module (that exists in the -current
kernel).
I do not want to to use the CURRENT so I fixed the code to work with the
6.1-RELEASE.. the main problem was the distorted sound it produces
The problem was that the realtek chip was not able to make dma
larger than 4096 bytes long a small fix in the hdac.c code did the
trick....
Just get the file http://www.k1.com.br/downloads/snd_hda.tar.gz
unpack it and do o make;make install
inside the directory created (you must have the kernel sources
installed)....
EnJoy....
