Hi, I am trying to have short latency on my computer. I am using the hda-intel driver and I am wondering about the output latency : - with a buffer size of 64 and period of 2, I get around 1.5ms of output latency - with a buffer size of 64 and period of 4, I get around 4.2ms of output latency ! I don't figure out this big difference.
Setting period size to 4 allows me to set buffer size to 16 and have an output latency of 1.2ms, whereas period size of 2 and buffer size of 16 gives me too many xruns (even with patched kernel). So I am wondering if buff/period size of 64/2 was my hardware limits and 16/4 settings only a trick handled by the driver ? I read that the minimum hardware buffer size was 64. Is it still true and is it meaningful to go under that number ? Which is exactly the relation between those 2 number inside the driver ? sorry for these newbie question... regards, matt _______________________________________________ Alsa-user mailing list Alsa-user@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/alsa-user
