>>> my system details:
>>> T520 ThinkPad
>>> 6 Gb RAM
>>> i7 quad-core CPU @ 2.8GHz
>>> RME Hammerfall DSP Multiface on ExpressCard adapter
>>> PlanetCCRMA on FC16 (x86-64)
>>> my observations so far:
>>> kernel 3.1.0-7.fc16.x86-64 ----
>>> jack runs reliably down to 64x2
>>> hdspmixer runs reliably
>>> kernels 3.2.17-1.rt28.1.fc16.ccrma.x86-64.rt AND 3.3.7-1.fc16.x86-64
>>> jack starts, but locks up very quickly
>>> hdspmixer locks with error: "HwDep ioctl failed. Metering stopped"
>>> any help sorting this out would be most welcome... let me know if there are error messages or other console output which would be useful!
>> Hmmm, weird. Which version of alsa-tools do you have installed? (rpm -q
>> alsa-tools to find out).
> but i'm not really sure if that's the culprit, or if it's a kernel thing that's throwing the hdsp, and the hdspmixer fail is just a symptom of that... on some other systems (with older kernels, mind you!) 1.0.23 was better for hdspmixer, so *maybe*. however, i do know there's still something else going on, because jack (jack2, btw) fails even if i haven't touched hdspmixer since a reboot.
further note: that alsa-tools version is from "updates". i just downgraded alsa-tools to the one in the fc16-ccrma repo (126.96.36.199-3.1.fc16.ccrma) and i still get the same problem with hdspmixer.
