Hi :)
how can I give my sound cards high priority on Ubuntu Studio Precise?
This is how it should be:
spinymouse at avlinux:~$ /etc/init.d/rtirq status
PID CLS RTPRIO NI PRI %CPU STAT COMMAND
384 FF 90 - 130 0.0 S irq/8-rtc0
1102 FF 85 - 125 0.0 S irq/18-hdspm
1123 FF 80 - 120 0.0 S irq/20-ICE1712
1135 FF 80 - 120 0.0 S irq/21-ICE1712
This is how it is:
spinymouse at precise:~$ /etc/init.d/rtirq status
PID CLS RTPRIO NI PRI %CPU STAT COMMAND
92 FF 90 - 130 0.0 S irq/8-rtc0
85 FF 85 - 125 0.0 S irq/18-ohci_hcd
89 FF 84 - 124 0.0 S irq/18-ohci_hcd
666 FF 83 - 123 0.0 S irq/18-snd_hdsp
1175 FF 82 - 122 0.8 S irq/18-nvidia
681 FF 80 - 120 0.0 S irq/20-snd_ice1
688 FF 80 - 120 0.0 S irq/21-snd_ice1
For more information take a look at [1].
Regards,
Ralf
PS: Sorry, HTML makes the terminal output easier to read and
crossposting, since this issue might not be related to Ubuntu Studio
only.
