Hi Miller, and others,
With ALSA audio output I get:
tried but couldn't sync A/D/A ^^^ repeated many times
audio I/O error history: seconds ago error type 3.00 A/D/A sync 3.00 DAC blocked 3.00 A/D/A sync 3.00 DAC blocked 3.00 A/D/A sync 3.00 DAC blocked 3.00 A/D/A sync 6.92 DAC blocked 6.92 A/D/A sync 6.92 DAC blocked 6.92 A/D/A sync 7.09 DAC blocked 7.09 A/D/A sync 7.09 DAC blocked 7.09 A/D/A sync 7.09 DAC blocked 7.09 A/D/A sync 7.09 DAC blocked 7.09 A/D/A sync 7.44 DAC blocked
I set the buffer size to as high as 500ms and still got >100ms audio dropouts every few seconds, which is obviously no good at all.
PortAudio with /dev/dsp works fine with the same settings, no dropouts at all, so I guess that's what I'll use for now. I have yet to try JACK, and OSS didn't work at all (no devices to choose from, which is strange because PortAudio works fine with /dev/dsp)

Hi Claude,
This is weird behavior indeed... what audio hardware are you using? I'm running nothing but ALSA these days and haven't had that kind of problem...

I noticed that the modem (which I don't use) and the Cardbus Bridge (which I don't use either) also use IRQ 7, but I don't know what this means.
