Hello,
I am currently facing a strange problem with ALSA and Jack. I play
electric guitar sometimes and I use my computer as a medium to
output the sound. For this, I use jack, with alsa as the driver.
Half of the time, everything is just fine, the audio output of my
guitar is just what it should be.
However, sometimes, the sound is completely low, distorted and with
a lot of cracklings and looks to have been produced by an awful and
very old synthesizer.
Could it be that you are experiencing xruns? (This is jackd's term for
a buffer over- or under-run in your sound card). xruns typically make a
popping or crackling sound. Qjackctl should show xruns in red in its
main interface.
