Hello,
How does this all relate to the snd-hrtimer ALSA module? Or is this a
software timer while hpet and rtc0 are hardware timers? This is a bit
uncharted territory for me and I like to get things straight for the
LinuxMusicians system configuration page
(http://wiki.linuxmusicians.com/doku.php?id=system_configuration), and
also for myself as I use MIDI a lot (Qtractor, seq24, Hydrogen etc.).
Best,
Jeremy

What a unhelpful error message! can't they at least include information
on the value that was supposed to be used?
same here, but the audio group has also the rights for /dev/rtc
We need the permissions of the actual device file (/dev/rtc0) , _not_
the link since the link permission only describes who is allowed to
follow the link.
But still I get the message when launching
Oostudio (openoctave /
oom).
You might have your settings for the maximum value set too low. What does
the following show:
$ cat /sys/class/rtc/rtc0/max_user_freq
On older kernels that should be:
$ cat /proc/sys/dev/rtc/max-user-freq
Also relevant:
$ cat /proc/sys/dev/hpet/max-user-freq
You can set these values like this:
$ sudo echo 2048> /sys/class/rtc/rtc0/max_user_freq
$ sudo echo 2048> /proc/sys/dev/hpet/max-user-freq
or set them in /etc/sysctl.conf
