Re: [linux-audio-user] Re: Stuttering via HDSP, Cardbus, Multiface?

Tim Blechmann wrote: CardBus bridge: Ricoh Co Ltd RL5c476 II (rev a8) I ran the spectrum of problems, but them main issue was that the card would not make sound. Sometimes the card was not recognized, sometimes the card was recognized, but the firmware would not load. Other times, card was recognized, firmware was loaded, but I would get awful sound out of it like the problems you, Timothy and Ico report. But that was the last step along the way, and I could attribute it to bad IRQ assignment from ACPI, if I remember correct. But that only happened after a significant amount of "voodoo" with the recognition and the firmware with Planet-CCRMA. By "voodoo", I mean things like this: there were times, espc with Red Hat, where it seemed to work only after power cycling both the laptop and the multiface, but that was not a real solution. Changing distros was the final voodoo, but it seemed to do the trick. You can search the archives of Planet-CCRMA list for "derek+HDSP" for all the gorey details of my saga there, as I kept them very up to date on my woes. TCI 1420 and 1440 are listed as problem cards by RME. TCI 1225 shows up ok, though, so I imagine a 1250 is probably cool too. I maintain to this day it is something between the cardbus controllers, their kernel-drivers or modules, or the configurations thereof which creates this mess. I don't think the ALSA-dev folks have much power to correct this problem, although I would bet that their understanding of the upstream problems might be more educated than ours. My guess, along with Ico, is that kernel-dev folks might be the best resource, if you can document the issue well enough. Which is hard when you aren't sure excatly where it lies. good luck, D. -- derek holzer ::: http://www.umatic.nl ---Oblique Strategy # 196: "What else is this like?"
