ft-991a internal audio bug

Can't setup ft-991a internal board audio

[M0PLT]

Graphical representation of the issue in 9.5.8. usbstream device is not found or not working.

Output can select the IEC958 device:

I am running Rocky Linux 8 and the package I have tried is a personal rebuild of the Fedora 35 source-RPM for EL8. If I start Fedora 36 as a virtual-machine in VirtualBox and connect through to the FT-991A, the same error is present.

Older versions certainly worked as I have used QSSTV with gpredict managing the doppler-shift to receive SSTV images from the International Space Station.

Example settings from WSJT-X. Setting alsa_output for the TI USB codec no longer seems to work in either WSJT-X or JS8CALL.

The alsa_input option is missing from QSSTV for RPM builds.

[M0PLT]

Possible work around. Set the Pulse mixer to use the USB Codec as its input, then set QSSTV to use PulseAudio. Start the receiver, and audio from the FT-991A shows up.

But someone know where is the problem?
