I don't blame Linux apps, I suspect that especially the PCIe slot
(chipset, mobo design) is less good. However, regarding to the issues
with Muse, yes, I suspect that it's the application. Ardour 2 and
Qtractor do run on my machine.
At the moment there's no difference between full preempt and preempt rt
kernels on my machine. It also doesn't make a (big) difference, what
graphics and what driver I use. At the moment it's the ATI with the
FLOSS radeon driver. In the past there often were differences when using
different graphic cards and drivers. In the past I needed to use the
kernel-rt, today I also can use the full preempt kernel.
Still maintained and used installs are Ubuntu and Ubuntu Studio Quantal
and Precise and at the moment I slowly set up a new Arch Linux, the
other Linux installs are not or seldom used:
$ grep menue /run/media/rocketmouse/q/boot/grub/grub.cfg
menuentry "FreeBSD"{
menuentry 'Ubuntu Quantal, kernel 3.6.5-rt14' {
menuentry 'Ubuntu Quantal, kernel 3.5.0-18-lowlatency
threadirqs' {
menuentry 'Ubuntu Quantal, kernel 3.5.0-18-lowlatency (recovery
mode)' {

menuentry 'Arch Linux Rt' {
menuentry 'Arch Linux' {
menuentry 'Arch Linux Fallback' {
menuentry 'openSUSE 11.2, Kernel 2.6.31.6-rt19' {
The only stable DAW I ever had, was Edubuntu 10.10, I never had a stable
DAW before or after Edubuntu Maverick, unfortunately I can't use the
stable setup with my RME HDSPe AIO, since it wasn't supported that time.
I used Maverick with the TerraTec ICE1712 cards only.
To be continued ...
