Hey All, I've been using Asterisk for a couple years now, but have always had some unsolvable audio problems. I get audio stuttering and popping quite often. Even if I have just one call up! The server is a Dual Duo-Core 3.0ghz Xeon Processor PC with 4 GB or ram. It just seems to me that this should NOT be happening. The server resources are nearly 98% idle. I've tried using the SLN audio file format, which does reduce the CPU usage when playing audio files, but it didn't help the audio quality. I've also tried putting my audio files on a RAM Drive and still have the same problem. I've also slimmed my asterisk system down to load only the modules that I am using via modules.conf. Now my question. I've heard through the grapevine that the Operating system running Asterisk can make a big difference in performance. I am currently running SuSE Linux Enterprise Server 10. A friend of mine actually talked to someone at Digium about this specific problem and they told him -not- to run SuSE. Is this correct? Has anyone else had any experience similar to this? I'm just wondering if Digium just wanted to push Asterisk Business Edition running on rPath on him, or if there really are some conflicts with SuSE that may cause audio instability. If so then it definitely would explain a lot regarding my poor audio quality problems. I would be happy to hear thoughts that any of you might have. Thanks so much!

Is this correct?Dunno about correct, but FWIW I'm using SUSE 10.3Alpha1. Haven't noticed any SUSE-specific problems. /Per Jessen, Z?rich
I have had this issue and my problem was my motherboard timing. i changed it to diffrent brand and that fixed the issue. BTW i dont use SUSE, i use CENTOS but i dont think it has anything to do with it.
