About a year ago, this forum helped me get my Multiface working via pci, and thankyou for that. But now I am having new problems with the cardbus. I could use help, links, or info on how to figure this out.
What I'm trying to do - get alsa to run 44.1k audio and midi with low latency, mainly in Pd.
Current problems - audio doesn't seem to be able to sync up correctly at first. If latency is below 25ms or samplerate is above 32k, I get bad popping sounds about once a block. This is happening in both Pd and Audacity.
Temporary fix - I can use the OSS emulation driver in Pd and get less than 5ms latency at 44.1k without xruns. But, midi is not recognized this way, and I can't use JACK. So, it is hopefully very temporary.
Equipment:
Compal Hel80 notebook
ENE CB-714 cardbus
RME HDSP Multiface II, older style cardbus
drivers have been loaded in Windows to update bios and whatnot.
Some errors that I don't pretend to understand:
##after I load hdspmixer
Looking for HDSP cards :
Card 0 : HDA Intel at 0xd2500000 irq 66
Card 1 : RME Hammerfall DSP + Multiface at 0x8c000000, irq 169
Multiface found !
1 Hammerfall DSP card found.

I am lost when it comes to troubleshooting ALSA problems... and I don't understand why OSS emulation works and ALSA doesn't. Please help if you can, it is appreciated a great deal.
