Hi all, I'm new to these forums, but have read through different topics on here frequently when I have computer problems. This issue I'm having now has pushed me to create an account and start seeking some help. Basically, I'll be using a program that connects to servers (to which other members are connected to, and we can communicate), and after maybe an half hour or so, suddenly others will be unable to hear me, and report my transmissions broken, and unreadable. I've found that if I go into the program's Audio Settings and switch from using Wave Sound to use Direct Sound, just in the Microphone portion of the Audio Settings, and click Apply, it fixes the problem and users can hear me again. However, then it seems like 20 minutes later, the same thing happens. So I do the same thing, and switch it back to Wave from Direct Sound. Problem solved. Then again, 10-15 minutes later, and same fix for it, just switching it back to whatever it previously was, and then when it happens again, back to the other way, and so forth. It might be my imagination but it seems initially all is fine, then the problem starts, and continuously gets worse and worse (shorter time span inbetween needing to switch back/forth) as time goes on. I should note when this happens I do NOT have Skype, Teamspeak or any other VoIP program open on my computer that I know of! I have another program that similarly communicates with users and it also has the same symptoms. For the record both programs I'm using are called VRC (metacraft.com/VRC/) and Squawkbox (squawkbox.ca)...they are part of a flight simulation community called VATSIM. I'm operating on Windows XP and using a Linksys router. I don't believe it has anything to do with the router though because I am using a desktop PC, and when I try using the VRC program on my laptop (which is wirelessly connected to the same router as the desktop), I have no issues. I am using a SoundMax HD Audio onboard soundcard with an Asus motherboard. Any help is appreciated!
