I was able to change slots. Also try to keep some distance between the video card and the audio card. (if you can) See if you can set IRQ in the bios for that slot to something else if there is only one. I find the same thing with USB audio. I have to find a USB plug on my laptop that does not share irq with anything else and only plug the audio IF in that one plug. > Fine system says: > > 17: 0 0 0 0 IO-APIC-fasteoi > ICE1712 Nice. >> cat /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor > > Xrunning system says: > > ondemand > ondemand > ondemand > ondemand > ondemand > ondemand > ondemand > ondemand What may help if you don't want to use performance is to set it to user and then set a lower than top speed. I seem to get less problems setting my system to 50% speed than with the (faster) ondemand setting. cpufreq-set and cpufreq-info are great to play with this stuff. the -info one will tell you what frequencies you can choose from. I found choosing the exact frequency didn't always work, slightly higher or lower would though. Play with it. Read the man page. My laptop runs at 1.6Ghz, but also has 1.33, 1.06 and .8. I can do a lot more than I would think at 800Mhz as it turns out. rtirq can help. If used wrong it can make things worse... for example the stock setting is bad for FW or USB audio IFs. It comes with the snd first or second. as someone else says in another message put snd_ice1712 and then snd after. This will put your internal IF in it's proper place, second. I do the same with USB cards. I find out which USB plug has no other irqs with it (USB3 on mine) and put : usb3 snd usb as the order. This puts my external audio first, then the internal crap audio and then whatever other usb stuff there is (in a laptop that includes webcam in the lid and SD reader and maybe other things too... take a look through dmesg for all the stuff that is USB) Be aware that putting: snd-ice1712 snd will put all that other stuff on irq 16 between your ice and your internal card and you may wish to explicitly make them lower. Check your priorities after you have it going: ps -eLo pid,cls,rtprio,pri,nice,cmd | grep -i irq Look at the third column over. -- Len Ovens www.OvenWerks.net _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/listinfo/linux-audio-user
