[Asterisk-Users] Horrible BUZZZZ noise when sounds/music play on SIP phone?
Hi, I've recently set Asterisk up, 1.0.2 version. With 1 x X100P card and 1 SIP phone. I've noticed some horrible buzz/rasping type of sounds! These seem to occur when * is trying to play back some audio or sound to me? E.g. If I have an exten rule which plays one of the music on hold files when I dial 800 lets say, I get a really loud buzz for about 2 seconds and then the music plays. E.g. 2. If I dial 500 to connect to Digium, as the call is connecting I get the same loud buzz noise for 0.5 seconds or so. Not sure where this is coming from? I did a search on the wiki for buzz/hum/rasp but could not find anything. Thanks Mike

Check to see if you are sharing an interrupt on your X100P card, take a peek with " cat /proc/interrupts (on linux at least) :) Dave
