Kernel Panics in 10.5.2
 
Using Vent 3.0.1 under 10.5.2 on a MacBook Pro with a Logitech headset.
I get Kernel Panics randomly, but usually after vent has been connected to a server for at least an hour. This problem did no occur with Vent 3.0.0

Are you running any other programs at the same time, especially anything that might be monitoring the microphone?

matthoff 03-26-2008 12:27 PM

I am running World of Warcraft. I have vent set up to send the audio to my MacBook speakers and the microphone is set to my Logitech headset. I am not running another app that uses the microphone. I do have iChat running in the background but I don't use it while vent is open.

Flagship 03-26-2008 02:43 PM

Even though iChat isn't being used it could still be interacting with the microphone.

Shut it down before you play WoW and use Ventrilo, if only to see if that stops the kernel panics.

matthoff 03-26-2008 08:00 PM

It just did it again. I had WoW, Firefox and Vent running. Nothing else.

I'm going to be working on the sound system to implement SFX for the Mac client over the next few weeks, and since I think this kernel panic is caused by the sound system implementation I'll take a look at it while I'm in there.

Strange, it worked fine until 10.5.2. Then again something might have changed in their specification and I didn't know about it.

In the mean time you might also go into setup-voice and uncheck "enable outgoing voice" option just to see if that prevents the panic. This of course will prevent you from transmitting but you will still receive voice streams.

Let me know if that helps as it would help to narrow down the search.

Thanks,

If you have a different headset plugged in, do the panics still happen?

matthoff 03-29-2008 02:32 PM

I don't own a different headset and the panics do not occur on a regular basis so it is very difficult to pin it down.

Out going sound quality AND panics
 
Hello, I have the same problem on my MacBook using Logitech usb head-set. But not just panics, people also complain that my out-going transmissions randomly start echoing or sounding like a 'robot'.. If I use the sound test in setup, my transmission quality returns to normal, or if I close and restart ventrilo. This happens quite regularly and is very annoying.

Also after running ventrilo for a longer period it will cause a kernel panic, this takes an hour or more to happen, but it will always eventually happen and appears to be caused by transmitting, since if I leave the mic muted for long periods it doesn't panic, it's only when actually transmitting.

I don't run any games on this computer, only iChat, msn, mail and vent.

Best thing for you guys to troubleshoot is to try a different headset.
