Mike Jumper closed GUACAMOLE-236.
---------------------------------
Resolution: Invalid
I've reproduced this effect by testing with Audacity running within an RDP
session, however the problem does not seem to be due to Guacamole. Calculating
the number of bytes that should be recorded for a given number of seconds, I've
verified:
# The Guacamole client sends the correct number of bytes
# guacd receives and processes the correct number of bytes
# The {{AUDIO_INPUT}} implementation within Guacamole's RDP support processes
and sends the correct number of bytes
As the audio recorded by Audacity isn't faster in the sense that audio is being
received overall at too slow a rate (this would result in high-pitched playback
as well as faster playback), it looks more like Audacity is simply dropping
part of the input, resulting in a choppy recording that seems faster. The data
actually sent by Guacamole is correct.
Recording using a different tool, such as an online voice recorder running
within Chrome within the RDP session, the recording sounds fine.

> With SSL enabled it works with Google Chrome too. What's still rather weird
