Hello
I just installed WFVIEW on PC Linux. I encounter problems on PC server. For the moment I have a little audio on the PC client (very low).
On the PC server at the launch of WFVIEW sometimes I have USB AUDIO CODEC on TX Audio Outpout but often it does not appear by selecting PORTAUDIO.
It is the only port that allows me to have audio on the PC client.
In addition on Radio Setting the USB going to MIC by reconnecting radio.
What error i can make?

Hi Bernard,
I don’t know why the USB output does not show up. I would try Qt Audio as well as RT Audio to see if that helps any. Disconnect from the radio. Select the alternate Audio System (Qt or RT in your case). Wait a moment or two, then, check the Audio Input and Audio Output combo boxes in wfview to see what is there. It takes a few seconds to get the list of devices sometimes.
You can also try this shell script, it will list information about the audio devices, good for testing:
https://gitlab.com/eliggett/scripts/-/blob/master/radioscan.sh?ref_type=heads
commands to save and run the script:
wget https://gitlab.com/eliggett/scripts/-/raw/master/radioscan.sh?ref_type=heads -O radioscan.sh
chmod 755 radioscan.sh
./radioscan.sh
It may be that the reason the device is disappearing has to do with inadequate USB cable shielding, we have seen it here that many inexpensive USB cables are not properly shielded (test with a multimeter between the USB connector’s outer metal shells for continuity). Rebooting the radio may also help.

I have a script that can reset the bus if it gets whacked by rfi. let me dig it up
Hello Elliot
Thank you for your answer. I will already check the cable and if necessary replace it, I have several of this type.
I have already tried different ways to adjust the audio and for the moment I stay on a failure.
PORTAUDIO gives me the best solution when I can put USB Audio Codec at output. I will continue to look.

Hello
The loss of USB Audio Codec is done without radio transmission. This happens after I closed and reopened the WFVIEW program. Without modification of parameter. So the RFI is not in question. I have been using this link PC IC7300 for several years and I have never encountered a problem with CQRLOG or FLRIG.
This morning I disconnect and reconnect the liaison USB cable and after several connections Deconnection of the WFVIEW program the USB Audio Codec Output did not disappear from the list.
On the other hand in Radio Setting when I reconnect the radio to the progrmm: Data mode Inputs Data1 goes by itself from USB to MIC.
I’ll keep you posted from the future

the tool also will work if there is no transmission is involved.
next post contains the simple source code to reset something on the USB bus.
Here there is a line that finds out what device was connected and is used as argument to the usbreset program to reset that particular device.
example:
sudo usbreset /dev/bus/usb/lsusb -d 0451:2046 | cut -d ":" -f1 | cut -d " " -f2/lsusb -d 0451:2046 | cut -d ":" -f1 | cut -d " " -f4
and the source of the usbreset executable – author unknown. wanted to write it myself but found this snippet.
/* usbreset – send a USB port reset to a USB device */
#include <stdio.h>
#include <unistd.h>
#include <fcntl.h>
#include <errno.h>
#include <sys/ioctl.h>
#include <linux/usbdevice_fs.h>
int main(int argc, char **argv)
{
const char *filename;
int fd;
int rc;
if (argc != 2) {
fprintf(stderr, "Usage: usbreset device-filename\n");
return 1;
}
filename = argv[1];
fd = open(filename, O_WRONLY);
if (fd < 0) {
perror("Error opening output file");
return 1;
}
printf("Resetting USB device %s\n", filename);
rc = ioctl(fd, USBDEVFS_RESET, 0);
if (rc < 0) {
perror("Error in ioctl");
return 1;
}
printf("Reset successful\n");
close(fd);
return 0;
}
Hello
Thank you for your help
But not having obtained a positive result after many tests I will resolve to give up the project.
Nothing works despite the time. The TX goes into emission but there is no modulation. On the customer PC a red logo representing a microphone appears in the PC Linux stains bar when I connect WF to the radio. I don’t know if it’s normal.
I stop there.
Thank you to the designers of the project for the time devoted to the whole radio community.
