Some internal sound interfaces are not detected correctly, and they seem to be capable of using 24 bit or 32 bit audio words, but only work correctly with 16 bit audio words. You can use the --short argument to jackd to force it to try 16 bit first. Also verify in the jackd output that it starts at the sample rate you expect, some internal sound interfaces only run at 48kHz, and if you attempt to start jackd using 44.1kHz sample rate it will fall back to 48kHz. -- Chris Caudle _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx https://lists.linuxaudio.org/listinfo/linux-audio-user
