1.0.0pre2 - ymfpci

1.0.0pre2 - ymfpci

[tom burkart]

The problem I reported several times is still present.

Problem:

Toshiba Tecra Notebook (Yamaha YMF-744B) still has scratchy,
unintelligible sound output.
kernel 2.4.22, alsa-driver 1.0.0pre2

Yet, the ymfpci kernel module (OSS) works fine.

Please advise on how I can help to debug this.

tom.

hmm, that one is a long standing bug.
i thought you got the silent output, but now you get a scraching
output?
anyway, please show again the register dump via proc file, and
hw_params in /proc/asound/card0/pcm0p/sub0.  both files should be
checked during playback.

Ok, I must have just woken up...  The scratchiness of the sound are the louder
parts of the music (so it appears anyway).  So I am postulating that for some
reason the lower 8 bits do not make it to the chip/output.  This is a guess, but
who knows, maybe there is some truth in it...
