Do you really need plain alsa by any reason?<div><br></div><div>If not, switch to jack audio server, then in jack you can configure the desired "latency parameter" easily (use qjackctl as GUI frontend for jackd itself).

<br>
If I go to media/audio setting and try to set a delay higher than 50ms, I get a lot of "tried but couldn't sync A/D/A" messages and then "audio I/O stuck... closing".<br>
<br>
This is on Ubuntu 10.04 with Pd Extended 0.42.5, with ALSA.<br>
<br>
In windows I used to increase the delay when I had cpu-heavy patches (or when some other cpu-heavy application had to run on the same computer) in order to have a bigger buffer and less dropouts and it used to work seamlessly. I got more latency, obviously, but it worked better (less dropouts), not worse.<br>
<br>
Why do I get these errors, what do they mean and why should a higher delay value trigger them???<br>
<br>
thanks<br>
m.<br>
