Subject: alsa-utils: aplaymidi plays but 1 note: conflict with chrony
Package: alsa-utils
Version: 1.0.11-3bpo1
Severity: normal
*** Please type your report below this line ***
aplaymidi plays only the first note of a midi file. Strace shows that it
stops after
ioctl(3, SNDRV_SEQ_IOCTL_SET_CLIENT_POOL, 0xbf8f1130) = 0
However the cpu becomes very busy and top shows that this abnormal
activity is
associated with chronyd.
Stopping chrony resolves the problem.
aplaymidi will usually function after restarting chronyd.
I suspect this problem has been present ever since I installed chrony
several months
ago. I am currently running a locally compiled stock 2.6.18.3 kernel.
Similar problems with pmidi, playmidi etc.: I suspect this is an alsa
driver problem
rather than application level.
