Sorry to bombard the list with questions, but it seems I am running
into every possible issue along the way. Hey I've got a great idea!
Better documentation might help! : P
Anyway, my question this time is this:
I am successfully using an AUHAL to get input from any audio input
device connected to the machine now. However, this is only when I
build as a deployment version. When I build as development I receive a
seg fault in my InputProc for the AUHAL for no apparent reason.
Everything looks fine when I check it out in the debugger. All of the
variables that I am giving to AudioUnitRender are correct (as far as I
can tell). I still manage to get a seg fault that looks like this:
#0 0xffff8a48 in __memcpy
#1 0x0074724c in AUBufferList::CopyBufferContentsTo(AudioBufferList&)
const
#2 0x007471b8 in AUBase::DoRenderBus(unsigned long&, AudioTimeStamp
const&, unsigned long, AUOutputElement*, unsigned long,
AudioBufferList&)
#3 0x006c9eb0 in vtable for CACFLocalMessagePort
#4 0x006eb8b0 in SystemOutputAUEntry
#5 0x006cda60 in AUGenericOutputEntry
#6 0x00749038 in
ComponentEntryPoint<AUHAL>::Dispatch(ComponentParameters*, AUHAL*)
#7 0x90281278 in CallComponent
#8 0x91a90f20 in AudioUnitRender
#9 0x0009b97c in InputProc at AudioInput.c:471
#10 0x006d1778 in AUHALEntry
#11 0x9072360c in IOADevice::CallIOProcs(AudioTimeStamp const&,
AudioTimeStamp const&, AudioTimeStamp const&)
#12 0x90723a60 in HPIOThread::PerformIO(AudioTimeStamp const&)
#13 0x90722c14 in HPIOThread::WorkLoop()
#14 0x9073919c in HPIOThread::ThreadEntry(HPIOThread*)
#15 0x907391e0 in CAPThread::Entry(CAPThread*)
#16 0x900246e8 in _pthread_body
Yes, the AudioBufferList is created and allocated properly. And they
are huge just to make sure that there is enough room.
I'm confused. Last week everything seemed to be fine in both modes.
Thank you so much for the help that I have received on this list.
