portaudio: assertion failed when opening audio device full-duplex

[mressl@…]

The following initialization error occurs when using portaudio under Mac OS X 10.6.7 on a MBP, and opening the default audio device in full-duplex.

Assertion failed: (sizeof( UInt32 ) == sizeof( long )), function ringBufferIOProc, file src/hostapi/coreaudio/pa_mac_core.c, line 1713.

This seems to be a problem from the 32 to 64 bit transition. It seems that only a patch in pa_mac_core.c in line 1713 is necessary.

I can help with that. Please contact me at mressl@….

What steps are necessary to reproduce the problem?

If you can provide a patch to fix it, please attach it to this ticket.

This could easily be fixed upstream already; the version currently installed by the port is 3 years old.

I just noticed the latest PortAudio is 20110326. Download link is:

I will try to compile the latest stable release, and see if the error is gone. Depending on this, I will suggest updating the portaudio port to this latest release.

Thanks. Marc.-

Good news.

I can confirm the problems are solved when updating to the latest portaudio build. The download link is:

You can use ./configure --enable-mac-universal, to enable a universal build.

I hope this makes it through in MacPorts soon, it has been so useful to me!

[ryandesign (Ryan Carsten Schmidt)]

Configure arguments like --enable-mac-universal are usually unnecessary in MacPorts and most probably do not do the right thing in MacPorts (i.e. probably introduce their own ideas about what architectures to use instead of using our universal_archs).

If somebody wants to update the portfile and supply a patch here, that would be great.

I'm sorry for my ignorance, but what would be needed is updating these file, right?

• trunk/dports/audio/portaudio/Portfile​
• trunk/dports/audio/portaudio/files/patch-configure​

I will try to work on this, and upload here. Best wishes,

Marc.-

Replying to mressl@…:

I just noticed the latest PortAudio is 20110326.

An update to this version has just been submitted in #29429.

[ryandesign (Ryan Carsten Schmidt)]

I've committed that update; please see if it helps this problem.
