Thank you for this, I hadn't noticed it! I've tried checking out the
audiohooks branch and it actually does the volume thing I was looking
for... But...

"Unfortunately" you are quite right ... I can't deploy the audiohooks
branch for productive use. I've done some testing with it, and it
segfaults quite often, especially with IAX2 channels.

I've also tried porting over this function to 1.4.2, but to no avail.
What I've done:
- added func_volume.c/.h
- added audiohook.c/.h
- religiously modified channel.c/.h according to the SVN revisions made
by "file" in his audiohooks branch, in order to add audiohook support to
it
- modified the Makefiles

I manage to compile it, but when executing Set(VOLUME...) it doesn't
change the volume, and when the call ends it segfaults. I guess there
are too many differences between 1.4.2 and this particular trunk to
adapt it. Or is there something obvious I might be missing which could
help?

Is there a chance that this will make it to a "final" release?

I'll contact you off-list...

Oh, and yes, we stay in the media path all the time... Otherwise I
wouldn't have brought up the question :-)

Thank you everyone for your suggestions
