I sent this to mobile about a week ago, but I realized that I guess it
really needs to go here.  So here is the message again (for those of you
who have already seen it that is).

I have discovered a slight problem with the YMF744 drive under
4.1-STABLE.  I am running on a Sony Vaio PCG-XG18 as of a few days ago
(last weekend to be exact), and have found that when playing realaudio
streams that some of them come out with just white noise, while others
come out sounding fine.  So far what I have been able to determine is
the difference is one that works is 32k stero music, and the one that
doesn't is 16k music (whatever that means).  I believe this is probably
mono related (I had a similar problem with Linux)...  

Here is the information...

pcm0: <Yamaha DS-1E (YMF744)> port 0xfc8c-0xfc8f,0xfcc0-0xfcff mem 0xfedf8000-0xfedfffff irq 9 at device 9.0 on pci0

I have actually proven this to be mono related.  I installed mpg123 and
if I execute "mpg123 -m file.mp3" I get white noise, and if I execute
"mpg123 file.mp3" it plays fine.

Thanks,

Greg
