I mean, when for example I'm adding 2 sine waves at full amplitude in
one audio queue, their max values are 32767 + 32767 (or -32768 + -
32768), and that creates heavy clipping.
if I use 2 audio queues, and have a full amplitude sine wave in each
queue, I don't get any clipping.
My understanding is that the audio queue gain is by default at 1.0
(maximum), so how would I make it louder?

Of course you can.
If you are combining multiple files into one queue and getting a
different result than when the system combines multiple audio
queues, then there is either something wrong with your code or your
perception. I suppose it's possible that you're listening on a
laptop, and the built-in audio compensation is reacting differently,
although that is unlikely, but if you use the digital outputs or a
well-known audio interface, then you should be able to get identical
results either way. There is a Playback Gain for each Audio Queue,
have you examined these? Unless the overall graph has some kind of
dynamic plugin inserted, there should be no automatic gain with
Audio Queues.

Bump,
can I reach the same volume with one audio queue as I can with
multiple queues?

I just added the buffer signals into one audio queue (which clips).
Is there any way to achieve higher volumes with just one audio
queue? Like, is there a volume setting that I can increase?
