This is actually a known issue; many of us await a fix for it. On my computer, when I/O goes up, the sound plays at about 0.7X the actual speed it should be, making it sound "robotic." People with Athlon XP's are even experiencing this, when trying to burn CDs at 4X. I'm not sure what code is at fault, but I assume/hope that the problem will be gone by 5-STABLE, perhaps even 5.1. For now, I'm not sure what to do about it, I'm just trying to be patient. -Craig ----- Original Message ----- From: "Wade Majors" To: Sent: Tuesday, April 15, 2003 5:09 AM Subject: Adjusting pcm buffersize? > Hi, I am having problems with my soundcard that I think might be fixable > by increasing the buffersize, but the sysctl that reports the buffersize > is readonly. > > Basically, even when there is relativly mild hard disk access (like a > large cvsup) I start to get underruns (as reported by a verbose > /dev/sndstat).
