Hi all

I mostly listen to 80s radiostations from Shoutcast.
My experience shows that most 128k streams are ok.
I.e. I can listen to it for hours.

There are a few where the Slimserver cannot connect
at all, but that might be because the station is
shut down or the link is already invalidated.

The few stations from Shoutcast I tried with higher
sample rates (160k, 192k, 300k and 320k) did not
work. The buffer would fill up initially, but as
soon as the music starts playing the buffer would
go towards empty.
I don't think the limitation is on the downstream,
since measurement shows about 1896 kBit/s for my
downstream. (Cable)
I also tried one station (128k) from www.somafm.com
and I do not see the 75% problem, but the stream
would die within a few minutes and never recover.

Slimserver 5.0.3 (CVS from 1/11) runs on a Linuxbox
(SuSE 9.0) with about 384MB and 533MHz.

I tested with a Squeezebox.

File 1 - buffer fills to 100%
File 2 - buffer fills to 75% (lasts 2o minutes)

The stream stuttering problem is definitely network-related. I tend to
have problems with the Radio Paradise 128k stream, but their 64k stream
will play for as many hours as I can listen. Similarly, I see
occasional problems with Groove Salad 128k, but RadioIO Eclectic and
Accoustic play at 128k fine.

Ok using the above pls, with the "File 1" entry have been listening non
stop to Groove Salad for over an hour with no stutters ...

So, can someone explain the difference between the 'File 1" & "File 2"
entries & is it relevant ??

Cheers

Yeah, I just listened to http://www.weenradio.com (presumably a pretty
unpopular station as I don't know many other people who like Ween) on my
slimp3 for thirty minutes at 128K with no issues. I wonder how much of
this is Slim Devices taking heat for Internet radio's sucky technology.

Good point.

RP has been reliably unreliable tonight, so I took the chance to do some
'sperimentin'. I renice'd slimserver to -20 and it took a little longer
for the stuttering to start. Doubling MAXCHUNKSIZE to 65535 didn't seem
to have any effect. Maybe I should look into a Gentoo gamer kernel. I
think that one has the low-latency patches.
