As a side note, when having problems like this it can be nice to compile
and run wsjt-x in an isolated container, with known and controlled
system environment:

This is tested by me on RPi 5 as well.

Hi Kari,
What's the length of the IC-7300 output device name?
There doesn't seem to be much consistency in the size of card_name in
the pipewire alsa plugin. But, if the name gets truncated, wsjtx should
fail on the amd64 as well and doesn't. I'll ask on the pipewire-devel
list.
spa/plugins/alsa/alsa-acp-device.c: char card_index[16], card_name[64], *p;
spa/plugins/alsa/alsa-pcm.c: char card_name[64];
spa/plugins/alsa/alsa-pcm.c: char card_name[256];
spa/plugins/alsa/alsa-pcm.h: char card_name[128];

Hi Steve,
Pipewire may be the culprit here.
I'm currently running WSJT-X on a Raspberry PI4 with Raspberry OS 12
(
bookworm ) 64bit
without issues.
I'm using IC-7300 but FT-710 should be similar when it comes to
audio.
If you open terminal and enter "ps -fjH -u $USER", do you see a line
"/usr/bin/pipewire-pulse" there? This is ( I think ) some kind of
brdige
allowing pulse applications to use pipewire.

Hi Kari,
It's installed on both systems.
Some more evidence:
I can run aplay and output to the fig's sound output device without
error. However, if I run wsjtx with the audio output set to the
hdmi
device, when I run aplay, I get the same "no such device" error.
I don't this is a wsjtx issue, rather a problem in pipewire. I'll
look.
I'm especially suspicious of the rig's long device name.

Hi Steve,
Do you have "libqt5multimedia5-plugins" installed?

Hi,
No problem on Ubuntu 24.04 on an amd64, but no audio on RPi 5
with
the
same OS. Receive works on both.
I rebuilt wsjtx so the images are identical on both (2b9d65).
The settings are identical.
The sound output name is
"alsa_output.usb-C-Media_Electronics_Inc._USB_Audio_Device-
00.analog-

If I set wsjtx audio output to the hdmi audio device, I get FT8
tones
and no complaints in the log.
The rig indicates transmit, but no audio, so no RF.
Any suggestions on tracking this down?
I tried uncommenting some of the qDebug calls, but can't
find/enable
the output.
