[gentoo-user] Choppy mp3's via wireless connections...

[Jerry McBride]

Anyone have an idea for this one??

I've been experencing choppy mp3 playback when running wireless. Hardwire 
playback, via cat5e, is perfect.

The server/client involved are gentoo. The software versions are: kde 3.2.0, 
kernel 2.6.2, samba 3.0.1 on both ends. Hardware of the client is a presario 
700us running the alsa snd_via82xxx driver with the ac97 codec. I use alsa as 
the OSS drivers won't detect the laptop hardware.... Orinoco Gold pcmcia card 
which is a 802.b running at 11mbit, processor is an AMD 1.2gig with 256meg 
memory...

Anyways, the problem shows it's ugly head anytime I try to play mp3's when 
running wirelessly. Using KDE and JUK, the mp3 begins to play like normal 
then pauses briefly and begins to play again. The same thing happens with 
MPG123 or MPG321 when run without KDE. This occurs all the way through the 
playback. During the pauses, I have noticed that there's a bit of activity 
with the connection led's of the Orinoco. I would assume that the player runs 
out of data stream and pulls more off the server via the wireless. When this 
happens, the music playback stops until the buffer fills and then playback 
resumes nornally...

If I unplug the Orinoco and plug into the network viat cat5e, playback is 
perfect, no drop outs or any problems...

I've dug all around the net, looking for a way to either increase the buffer 
size in the orinoco or in juk... I've looked for ways to increase the 
priority of the pcmcia-cs drivers... I've tried to renice the involved 
processes, but no change is noted.  I've expiremented with the buffers in 
samba.... I've done as much as I can do to iron this one out and now I'm 
asking for a bit of help from anyone that may have a solution.

Thank you, in advance.
