Since I don't own the card in question, I cannot test the patch and
simply trust your word here.
OTOH, I have to admit I don't fully understand the patch. What you're
doing is to increment the number of output channels in case you have an
additional input module.
The input module is handled in HDSPMixerCard.cxx. Is it just a side
effect? Because semantically, it is wrong to create output destinations
just to get input channels rendered.
Why is hdspmixer segfaulting? Do you happen to have a backtrace or
explanation? This should be part of the commit message.
Minor nitpicking: I'd prefer (foo || bar) over (foo|bar). Sure, both do
the trick, but the first seems easier to read to me.
For the final patch:
Basically: proper commit message and sent to patch at alsa-project.org),
so your attribution will always be kept.
