From: Raymond <[EMAIL PROTECTED]>
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) ...
Huh... "normal priority"! You know... I haven't really understood much of what's in all of Winamp's preferences/settings until setting up some plugins recently. Way.. way.. back I had looked at that 'Process proirity class', and the "NOT recommended' warning there scared me from even experimenting. But setting it to 'high' >does< help. Just don't know how reliable it'll be. As I write, Winamp's already had a couple popup errors.... so.... more testing with that setting I guess.
But I wonder why you weren't having the problem. I had the same problem with the stock Win98 installation on the L100 before I installed W98SE hoping to clear up some other things.
I also haven't really found much of a difference with the filters
Which filters? Ones for the OPL3-SAx chip like in that download from Yamaha I mentioned? Or something in Winamp I've missed? I'm guessing you mean the Yamaha sound settings for various kinds of speakers I see in Toshiba sound driver. I thiink that special driver from the Yamaha website had accoustic enhancements, I might be wrong. What whatever it was, the audio only really sounded the cleanest with the effects turned totally off. And at that point, I wasn't able to get the same non-enhanced level of output I can with the old Toshiba drivers.
I had a simiilar problem with the firmware on my NEX II MP3 player. With the EQ enabled, it created noticeable hiss at low level playback. But turn the EQ off, and 85% of the noise disappeared.
(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).
Huh.... I'll tell you what I've got my sights on is that Indigo PC card sound card from Echo for $130, about the best price I can find. But they say requirements are Windows ME/2K/XP and 128MB RAM. I've got to think that must be for the bundled software, >not< the card itself. I wrote them about it, but as yet haven't gotten a reply. If I could get really clean audio output from it, this L100 may be spending more if its time sitting over by the stereo.
Speaking of which, I wonder if there's any wireless hardware that could send audio output from a notebook to a receiver plugged into the inputs of a home stereo. It'd be slick to be able to mulititask on the Libby while its broadcasting quality audio to the hifi!
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) ....
Well, I'm getting stuck on the gapless output plugin, but that's configured to use the OPL3-SAx for audio playback. I see 'Wave mapper' in there & have no idea where it came from. I'll experiment with it. Beside gapless, there's the stock waveOut v2.0.2a OUT_WAVE.DLL that I started with.
also, if possible, you might want to try reverting to an older version of Winamp perhaps.
Heh... more than the gapless plugin, I'd have to be pried away from v2.91. It must have been released in the past couple years, as way back I remember browsing their website looking for the old v2x releases when they were 1st pushing the v3.x series up front. I still have v2.81 archived from back then that I've been loading everytime I reinstall the OS, or install it on a new HDD. If 2.91 was out then, I would have it, as it has a library component like Musicmatch's, something I can't do without these days. For quite a while there I'd been wishing Nullsoft would add that to the old v2x series, as it runs way better on the L70 than my copy of MM v4.0. It finally show up in v2.91.
Well, setting that priorty up to high has almost eliminated the stuttering. But as yet I haven't gone more than 6-7 tracks without Winamp halting and complaining about errors. Guess they knew what they were saying when they said it was "NOT recommended". But then I'd think they put the 'high' and 'realtime' settings there of some reason. :-?
