Slackware 14.1 Streaming Audio Trouble


I have decent wireless network connection. Streaming video works well, like from youtube, for example. But streaming audio from radio stations constantly stalls. It doesn't matter what app is playing the audio, could be from within browser or using xine or any of the other playback tools.

I've launched iptraf and watched the connection. It looks like some initial activity fills up the pipe, and that's it. So the audio plays out until the buffer is consumed and then nothing else. Sometimes, but not always, the connection times out and closes. Sometimes, it stays open and might play another spurt of audio much later.

I don't know what to check or adjust on this one. Previously, same laptop running Slack 13.37 worked just fine.

thanks in advance for any ideas

ok lets do some within browser tests to start the ball rolling?

click on link and hopefully you can play a 32 kbps link (science mainly voice)
http://freezone.internode.on.net/radio/#/news/551

assuming you can handle that now try a trance radio 256 kbps
http://freezone.internode.on.net/radio/#/difm/350

this should play in firefox or chrome

report pls

2) I would like you then to try vlc but before I "force" another app on you

what do you use?
OSS
ALSA
Pulseaudio

3) are there some radio stations you can not play?

what format are they?
eg m3u or pls .....which vlc should be able to handle as most others should as well

4) Have you tried streamripper?

good luck

EDIT

can you post the links causing you issues?

TIA

1) None of the links on those pages would play anything for me.

2) ALSA

3) I'm not really sure about the file format. But - I did try some streaming from a couple of places to see what give. So, from WABC radio, that stream works better than most. It would run for a long time, but every now and then, it pauses the stream.

I tried KSBR streaming. It sometimes works, sometimes not. For this, I ran xine as the player.

I tried to stream bellyup4blues using xine and this one fails very quickly.

In all cases, with iptraf launched, monitoring the TCP/IP packets, I can see my laptop and the far-end exchanging data. In all cases, I can see it just simply stop exchanging. The connection doesn't always close, just stuck. I haven't done any packet sniffing other than that.

Originally, I thought streaming video worked - but now think that too isn't so good. Longer videos, say 1 hour, also seem to stop at random times, with the connection closed.

One more thing - even browsing the web is slow. Before you go and blame the laptop, it is dual boot with windows and there is no problem at all there - so the hardware is sound. Also - previous Slackware 13.37 did not have this problem either.

I think the problem is not the applications (VLC, xine, etc) but lower in the network settings or maybe even the kernel? I'm not sure where to go next.

thanks

ok

but test you have flash
http://www.adobe.com/software/flash/about/

also your browser needs to do javascript as per my inspection of below wabc link

Quote:
<script type="text/javascript" src="http://playercdn.listenlive.co/templates/StandardPlayerV4/webroot/js/lib/libs.combined.js" defer="defer" use_cdn="1"></script>
2) there might be a geo-block on my links as you don't reveal which country you are.
I will assume US due to http://www.wabcradio.com/

can you play
http://player.listenlive.co/25211

which is 77wabc radio

3) I use google chrome and can't use the listennow button at
http://www.ksbr.net/#

but I can't play inside the web a random station eg
http://www.live365.com/stations/bofbm

4) I can also play by pushing the play embedded button at
http://bellyup4blues.com/

now we are getting somewhere.....see those 4 icons below the player?
3rd and 4th offer file links that end in .pls

download one of them....I chose third...claims to be winamp
the file saves itself with a name listen.pls

vlc can play it as it claims to be a shoutcast playlist (pls)
