I have problem with recording sound and compressing it with lame. I guess, that this may be a kernel tuning problem. When I do: $ mkfifo file.wav $ rec -c 2 -s w -d /dev/dspW -r 44100 file.wav & lame --preset cd file.wav file.mp3 sound recorded by lame is strange; small slices of sound are lost, and I can hear something like quiet knocking. My question is: how to get the best performance of FIFO's in kernel? Is the snd_emu10k1 driver complete and working? What I sould change with sysctl to get sound recording working good?
