[alsa-devel] hdspmixer segfault (1.0.24+)
Hi, I'm getting a segfault from hdspmixer using the current git alsa-tools (1.0.23 works, 1.0.24+ does not). See below for a backtrace. I'm running 2.6.33.x rt30, could this be the problem? (a dependency on newer kernels?)

I have fixed this bug a couple of days ago:

They still need to be applied to the alsa-tools.git, but if you like, you can grab the patches and verify they work for you.
Cheers

They do work in a first (remote) test. Thanks very much!! -- Fernando

But one of my users (in Planet CCRMA) still has problems with his 9652, apparently the output labels for that card are missing and that is confirmed by looking at the source (his card works fine with the 1.0.23 hdspmixer). I applied all your patches to current git except for the version number so ignore the 1.6 version printed. I'm waiting for a backtrace from his computer about the subsequent crash. See below for his message (and thanks for all the help!).

I updated to alsa-tools 1.0.24.1-1.3.fc14.ccrma per today's note. This does not yet fix hdspmixer as the following command-line invocation and response shows.

Indeed. There have never been labels, and now it's crashing, most likely because of dereferencing the non-existing label array.
Do you mind to try this patch? Maybe it's enough. If Craig feels happy to do some remote try&error, I can sort this out with him.
Right now, I'm simply assigning a stupid "1", "2" .. "64" channel naming, but maybe Craig can provide us with the correct output labels? I don't have access to a H9652, so I don't have the slightest clue how the ports are named. ;)
