I think it happened when bdflush flushing buffers, cause when I copy file to filesystem mounted with option "sync" sound not interrupted. Steps to reproduce: Play sound simultaneously with writing on HDD
I'm not a devel but since you haven't get an answer yet, I will try to help you. (but I'm not an expert) I had the same problem before, when I used kernel 2.6.2 When I got kernel 2.6.3, I patched it with ck patches which you can get here : http://kernel.kolivas.org/ These patch contain cfq scheduler and other things. Now I have no problem when I play some song, even if I copy a large file or if I run apt-get (which is really intensive). So I think it's not a sound driver problem but a io-sched related one instead. PS : I use directly alsa to play sound, I don't use any sound server like arts or esd
Thanks for advice, this patch helped me, but not enough :( It sounds much better, but I still hear interrupts, they are not so long, and not so frequent, but they are still here... May be need to make kernel not preemptible, I will try it...
*** Bug 2348 has been marked as a duplicate of this bug. ***
Not matter preemptible kernel or not preemptible. Interrupts are still there :(
In version 2.6.6 if I use cfq I/O sheduler, interrupts are stil there, but not so frequent.
Can you try a more recent kernel? 2.6.12-rc6 or 2.6.11.12? No activity in more than a year... Thanks, Nish
Seems like kernel 2.6.12 work fine for me... Thanks guys! P.S. Sorry for delay, I really forget about this bugreport... :-/
