why is card #2 being set to default?

why is card #2 being set to default?

[Mark Knecht]

Hi Alsa Developers,
   Why is it that on my new AMD64 system the HDSP 9652 is listed as default?

lightning ~ # cat /proc/asound/cards
0 [CK804          ]: NFORCE - NVidia CK804
                     NVidia CK804 with ALC850 at 0xda103000, irq 185
1 [default        ]: H-DSP - Hammerfall DSP
                     RME Hammerfall HDSP 9652 at 0xda000000, irq 209
lightning ~ #

   On my previous systems I believe that card 0 has been default. Due
to clocking problems with the HDSP 9652 with OSS emulation I never run
OSS on the HDSP 9652 and want sound from general apps to go to the
NVidia on-board chip. The output of that chip is hooked to an input on
the HDSP which drives the main D/A so I get the best of both worlds -
NVidia does the low-end OSS and Jack runs all day on the HDSP 9652.

   Except on this new system it seems to not work that way.

   I do not use any .asoundrc files.

   Technical stuff follows.

Thanks in advance,
Mark

This is^H^Hwas a bug in the hdsp driver.  When using the kernel
firmware loader, it registered the card before setting the card name,
so ALSA used the string "default" as card ID instead of the last word
of the card name.

The ID string has nothing to do with which card actually is the
default card.

Thanks Clemens. So this is just the word 'default' as a name and not
the card being the 'default' which does have a special meaning in Alsa
lingo? ue to major changes in the studio I haven't even hooked up
cables to this machine yet so maybe all sound is actually coming out
of the card I want to use. I just wrote since this didn't look right.
Thanks!

Even though it's very minor I'll submit a bug report. It would be nice
to have it use the card's name.

cheers,
Mark
