I don't think my experience is going to be of much help to you given I never actually had much trouble with it but I'll give it to you anyway ... at the time my L100 was a stock 166MHz with 64MB RAM (prior to overclocking) ... installed Win98 on it (normal install), installed Toshiba's drivers, installed Winamp (2.5x I think) and it played right off, even running stuff like Word, Excel, Matlab and the like ... likewise under 2k I can run it in the background and, when things get heavy things slow down but it hardly ever skips (and it's on normal priority) ... I also haven't really found much of a difference with the filters (but then for some reason my Fujitsu hard drive is electrically very noisy anyway so that probably drowns everything else out ... I get more noise through the internal speaker than through a set of unpowered speakers plugged into the speaker out port though).
Have you tried playing with the decode settings under Winamp? I do recall getting noise problems on my desktop when the decode frequency was higher than the sound card could manage (but then they released a patch for that and, in this case, the problem turned out to be specific to the SB Live) .... also, if possible, you might want to try reverting to an older version of Winamp perhaps.

Okay... I'm back. But I've got a audio problem I wonder if anyone's dealt with.
I can't figure out why audio playback for Winamp 2.91 on my Libretto 100CT is worse than it is on my 70CT. Both systems are running Windows 98SE with the appropriate audio sound driver downloads from online Toshiba Support.
This especially since the 100CT is a PI 166MHz system with 64MB RAM, and the 70CT a PI 120MHz system with 32MB RAM.
When I 1st got the 100CT, I assumed that with both systems tweaked to load nothing extra at boot besides 'systray' and 'explorer' in MSCONFIG, the 100CT would be able to play back MP3s while multitasking better than the 70CT.
But in reality, audio playback with Winamp stutters on the 100CT while multitasking common functions (starting MS Word, starting IE & browsing the net, etc.), where the same installation of Winamp on the 70CT plays back normally.
The difference is that on the 70CT, the the response time on multitasked applications slows down, but the audio playback stream is seldom interrupted. While on the 100CT, response time multitasking the same tasks on the 70CT is faster, but with the resulting audio stuttering from Winamp.
Hoping they might solve the problem, I recently experimented with replacing the Toshiba's sound drivers for the Yahamha OPL3-SAx chip in the 100CT with an 'updated' version directly from Yamaha:
http://www.yamaha.co.jp/english/product/lsi/us/support/downloads.html
But though the drivers provide more controls over audio playback, they introduced noise through their filters that reduced peak output level when the filters were disabled. Not caring much for the effects they provided, and being more interesting in peak, unenhanced output, I've gone back to the default drivers from Toshiba.
Now that I'm starting to compile a database of MP3s ripped from my CD collection, I'm more interested at working out this issue if possible. Any thoughts or suggestions would be most welcomed.
Thanks,
Matt
