On my snd-hda-intel board(nVidia MCP61), I have to increase the number of periods to overcome this sound. default of 2 increased to 3 and all was fine, in jackd -n 3. For arecord you might look at different than default buffer/period sizes. It's basically a latency issue. Other considerations are to give the audio group realtime permissions so things like ethernet traffic doesn't cause clicks and other distortions in the sound. /etc/security/limits.conf HTH, James |
