I was able to get FreeBSD working almost completely except for sound recording. The problem is that when you spec 44100 sample rate, you actually get 22050 with a lot of "digital noise", like a raspy buzz. I played with audacity and with a C program that I wrote and have used on several different systems with FreeBSD and they both had the same problem. I remember when I first tried to bring up the pcm driver on my Dell 4000 laptop with ESS, back about 4.1 days, I had a similar problem (not quite the same, but it was noisy recording with the sample rate being off, not by 1/2 , but perhaps 25% slow). When I upgraded to 4.5, this went away. I only mention this as it was a similar problem and perhaps the fix is similar?
