sound and jackd on the dell precision m65

In order to get the intel-hda soundcard to work properly it is imporant that the software modem is enabled in the BIOS.

To make jackd work without xruns, add the following kernel options to the boot line in your grub config: noacpi acpi=off.

After this jack runs fine with the following settings in qjackctl:

  • Realtime
  • H/W Monitor
  • H/W Meter
  • Frames/Period: 256
  • Sample Rate: 44100
  • Periods/Buffer: 3
  • Interface: hw:0

This gives a jackd commandline like this:

/usr/bin/jackd -R -dalsa -dhw:0 -r44100 -p256 -n3 -H -M
