I can hear it running on the machine at the office. The sound card on the box running mprime doesn't work in Linux, and it's a 486 anyway so it's doing factoring. The box at the office is a Pentium. phma _ Unsubscribe & list info -- http://www.scruz.net/~luke/signup.htm Mersenne Prime FAQ -- http://www.tasam.com/~lrwiman/FAQ-mers

Haven't bothered to fix it, don't use the sound that much. Doesn't seem to happen on my P3/450 at home, where I do use the sound a lot.

Mersenne: Interesting/Annoying Mersenne Side-Effect
Hello All, I've been involved in GIMPS for about 2.5 years now, several machines, OSes. Recently I installed prime95 on a IBM Intellistation Dual uproc. It seems my combination of soundcard+headphones is VERY sensitive since when I'm running 1/2 prime95s I can "hear" them chugging along on the headphones. There is a low volume high pitch periodic (2/s) noise emanating from the speakers. As soon as I turn prime95 off, it ceases. The volume setting has no effect on it. Has anyone else had this problem? I'm pretty sure its a faulty sound-card, just wondering if anyone had an idea on how to fix it. Thanks in advance.
