Hi Linux Audio Enthusiasts!
I'm a fairly long-time JACK user (more than a decade, anyway), but I
must admit I don't really know it that well. I'm seeking guidance with
the following situation.
I am hearing audio "drop-outs" (a second or two of silence) that seem to
coincide with this error in jackd output:
JackAudioAdapterInterface::PushAndPull ringbuffer failure... reset
The audio hardware is a Digigram LX-DANTE connected to the JACK graph
via ALSA device hw0,0. jackd --version is
jackdmp version 1.9.18 tmpdir /dev/shm protocol 8
Also, jackd output fairly regularly (several times per minute) shows
messages like:
JackRingBuffer::Write : consumer too slow, skip frames = 1024
and
JackLibSampleRateResampler::ReadResample error written_frames = 1020
Output available = 1022
Where the number after the "=" in the "written_frames" line is between
1020 and 1023, and the number in "Output available" is always two
greater than the previous.
I start jackd (as Linux user 'root') with the command:
/usr/bin/jackd --realtime --name default -d dummy -r 48000
And then add the Digigram client with the command:
/usr/bin/jack_load -i "-d alsa -d hw:0,0 -i 64 -o 64 -r 48000 -p 1024 -n
2" Digigram audioadapter
Thanks for any thoughts about these drop-outs! And please let me know if
there are other troubleshooting tools available.
Best,
~David Klann
