Re: [alsa-devel] HDA irq understanding

Hi,

Sorry, is your problem that you *do* get broken audio when you load the system, or that you *don't* get broken audio when you load the system?

I don't

Either way, PulseAudio uses RT prio to get higher priority than your load scripts, so this is used in PulseAudio <=> ALSA communication, but not in mplayer <=> PulseAudio communication.

In fact the first problems appears in gnome interface I'll do some SCHED_RR cpu loads applications.

For the 10 msec frequency, it looks like timer-based scheduling is turned off (or possibly mplayer is using very small buffer sizes?). You might get help with this in the pulseaudio-discuss mailinglist.

I'll do some test changing mplayer buffer.

Thx,
