<div dir="ltr"><div class="gmail_default" style="font-family:tahoma,sans-serif">Dear All, </div><div class="gmail_default" style="font-family:tahoma,sans-serif"><br></div><div class="gmail_default" style="font-family:tahoma,sans-serif">
Icecast makes it possible that our Community/Student radio station reaches online listeners and it's FM transmitter. Operating with little or not budget, I've set up our streaming several times. Lately we are experiencing audio glitches and dropouts out of nowhere (setup hasn't changed tremendously). Similar cases I found on the list and elsewhere don't give general troubleshooting procedures, so here is what's going on. </div>
<div class="gmail_default" style="font-family:tahoma,sans-serif"><br></div><div class="gmail_default" style="font-family:tahoma,sans-serif">Problem: Clients connecting to mountpoints on any server with same source get noticeable audio glitches/stuttering and audio dropouts (approximately every 120s). On rare and random occasions it normalizes. </div>
<div class="gmail_default" style="font-family:tahoma,sans-serif"><br></div><div class="gmail_default" style="font-family:tahoma,sans-serif">Resolving Steps: </div><div class="gmail_default" style="font-family:tahoma,sans-serif">
- Tried different streaming formats (OPUS, MP3, OGG) and source software (butt, opus-econder, Altacast)</div><div class="gmail_default" style="font-family:tahoma,sans-serif">- Different servers produce similar effects with same source. </div>
<div class="gmail_default" style="font-family:tahoma,sans-serif">- When streaming with alternative service (<a href="http://mixlr.com/">http://mixlr.com/</a> 96kbps MP3 over Amazon Cloud Services) no stuttering is present. </div>
<div class="gmail_default" style="font-family:tahoma,sans-serif"><br></div><div class="gmail_default" style="font-family:tahoma,sans-serif">Any ideas? Clock drift? How to solve it? </div><div class="gmail_default" style="font-family:tahoma,sans-serif">
Thank you! I'll be glad to update with progress or additional info if required. </div><div class="gmail_default" style="font-family:tahoma,sans-serif">Below are logs and all. </div><div class="gmail_default" style="font-family:tahoma,sans-serif">
