New subject: [linux-audio-dev] Major problem with RME HDSP/Multiface and a 64-bit AMD laptop

22 Mar 2004

Hi,

...
  wait ... this seems to be similar to the problem i
have with my hdsp ...
 i can't run it on my linux system at all, althouth it works fine with
 windows xp:

 can you try jack as super user with -R flag? 
I will try to next week. Right now I am in a bind until this coming Sunday. I will let you
know as soon as I am done.

...

 if you use an input signal, some of the input gets copied to the output
 if a sound application is running, which results some distortion ...
 could you start jack / pd, and try to use any of the input channels try
 several settings of hdspmixer... 

 the problem with my hdsp is definitely a cardbus driver issue ... from
 what i heard from people who tried to help me is, that there are some
 problems in mapping the memory from the kernel to the buffer inside the
 cardbus bridge ...
 the problem with the kernel driver for the yenta socket is, that it's
 not properly supported ... thomas charbonnel, who maintains the hdsp
 driver and i wrote a message to both the kernel and the pcmcia-cs
 mailing-list, but didn't get any answer...

 of course, it could be a problem of the cardbus controller hardware,
 that the windows driver may handle differently than the yenta-socket
 module for linux my machine has an o2micro cardbus controller, that,
 conserning rme's support may produce problems ... 
 i'm able to sell my notebook to my mother ;-) and get a new one, soon...
 the only reason, why i won't get an amd64 is that the notebooks that are
 equipped with this chip, have either ene or ricoh cardbus controllers,
 controllers rme warns against ... that's why i'll order a p4 inspiron,
 soon... 
I would encourage you to hold off for a couple months, of course if you can afford to
wait. It took me literally a good year on my old Inspiron 8000 (later replaced for 8100)
before most of the quirks were resolved on it (both Win32 and Linux-side). This is pretty
much the case with most of the new technology. For instance my newest toy, the
aforementioned m6807 by eMachines has been on the market for barely 2 months and it is in
dire need of a BIOS update. Hopefully one will be released by eMachines (although I am a
bit skeptical about this one as most of their other products don't have such low-level
updates available), but if not, there are plenty of other resellers that might since this
model is being rebranded by over half-dozen companies across the world.

...

 anyway, when i talked to thomas a short time ago, he considered going to
 the lad conference, i'll go there, and concerning the schedule, you'll
 be there, too ... maybe we could try to track this problem down and try
 to contact the kernel mailinglist again... 
Absolutely! Looking forward to meeting you!

...

 i hope that you will be more luck than i was ...

Thanks :-)

Best wishes,

Ico
