Hi.
I try to set up Fldigi on my F5KA radio, but I have issues.
Here is the latest part from the fldigi-alpha mailinglist, where I have
asked for help.
--------------------------------------- device #9
Name = Virtual Cable 2
Host API = Windows DirectSound
Max inputs = 8, Max outputs = 0
Default low input latency = 0.000
Default low output latency = 0.000
Default high input latency = 0.000
Default high output latency = 0.000
Default sample rate = 0.00
Supported standard sample rates
for half-duplex 16 bit 8 channel input =
8000.00, 9600.00, 11025.00, 12000.00,
16000.00, 22050.00, 24000.00, 32000.00,
44100.00, 48000.00, 88200.00, 96000.00,
192000.00
This is Virtual Audio Cable masquerading as a DirectSound device. This
is the input device that gives you the error.

This is the same device accessed via the MME API.
Please try again with the MME devices for both capture and playback,
i.e., not the "Virtual Cable 2" devices that are under the "Windows
DirectSound devices" submenus.
If this works we'll have to assume that VAC doesn't work well under
DirectSound, or that there's a bug in PortAudio's DirectSound backend.
I think what Brian achieves by forcing the sample rate is to avoid the
problem where fldigi tries to set a sample rate of 0.0 (the default rate
reported by PortAudio for VAC/DS). The toggle to "File I/O" and back
must be a way to reinitialise PortAudio. If you save the settings and
restart fldigi you shouldn't have to do this.
I'm not sure why PortAudio reports 0.0 for the VAC DSound device, or how
fldigi should handle this.
Does anyone here on this list have any solution(s) to the issue(s) ?
