Bug 656514

File: backtrace

I can confirm that hdspmixer (mixer for RME soundcards) segfaults (both fc13 and fc14 have this problem). I have released a package with a fix as part of Planet CCRMA as RME high end soundcards are used more often by pro audio users. 

(this has (AFAIK) nothing to do with the realtek hd drivers - to reproduce it is enough to try to start hdspmixer). 

Here is the patch (originally from Gentoo) that I have used to successfully resolve this issue:

*** Bug 566138 has been marked as a duplicate of this bug. ***

alsa-tools-1.0.24.1-1.fc14 has been pushed to the Fedora 14 stable repository.  If problems still persist, please make note of it in this bug report.

After updating to alsa-tools-1.0.24.1-1.fc14, my card is no more recognized when launching hdspmixer:

Looking for RME cards :
Card 0 : RME Hammerfall HDSP 9652 at 0xfbff0000, irq 16
Card 1 : HDA NVidia at 0xfbe7c000 irq 16
No RME cards found.

I reverted to alsa-tools-1.0.23-1.1.fc14.ccrma.x86_64 with:
yum downgrade alsa-tools 

And launching hdspmixer now says: 

Looking for HDSP cards :
Card 0 : RME Hammerfall HDSP 9652 at 0xfbff0000, irq 16
HDSP 9652 found !
Card 1 : HDA NVidia at 0xfbe7c000 irq 16
1 Hammerfall DSP card found.
