I would have expected these to be the other way around, since higher timer frequency should result in more accurate simulated sound card interrupts.
Do you have different CONFIG_PREEMPT* settings?
You could try compiling with the original CentOS configuration and switching settings until it breaks.
I'd have expected the same.
But it's not a problem between centos kernel and all of ALSA: the other drivers works well. Is a specific problem of snd-dummy.
Yes, CONFIG_PREEMPT* are probably different between the various kernels, and also the compiled kernel is tickless.
But, this is a problem only with snd-dummy.
What I would like, in the interest of users, is snd-dummy to be modified in a way that makes it working on the regular CentOS-RHEL kernels, because CentOS-RHEL users will not like at all to change their beloved kernels (you know... they like stable, boring and predictable behavior).
If it can be useful, I can give you (or any other developer) ssh access to a machine running centos.
Or, please let me know what I can do for providing useful informations.
