He had several problems. Here's what we did.
#1 Uninstall all sound drivers (with the remove files option). Reboot without
rig USB plugged in.#2 Tested his speakers and microphone (PC-based) to ensure
they worked using Voice Recorder -- this is a sanity check that your sound
setup works the way you think it should.#3 Plugged in rig and relabeled the USB
Codec drivers to make them easy to distinguish#4 Adjusted levels on Windows
Playback/Record cotrols to 0dB#4 Adjusted rig blaster to 12 o-clock position.#5
Adjusted rig USB AF level to then get 30db+ on the waterfall (not all rigs can
do this so this may have to be done from rig blaster)
The decoding problem he had was due the signal levels being low from the rig
and over amplified in the Windows controls. So that's why he was getting
intermittent decodes as any gain over 0dB in the Windows controls buys you
nothing so there was lots of quantization going on.
He also has latency problems on his older laptop causing dropouts on
transmission but they are very short so don't affect him a whole lot.

It could be useful to know what you/he did to resolve the problem in
case others experience the same problem.
