I'm trying to get my Signalink interface to work under Ubuntu running WSJTX
and can't get any audio into the software. I've set everything to use the
USB Analog CODEC but Joe's software doesn't seem to like it. Anyone found a
work around?

Are you using pulse for audio ?

Have you read this ?

interesting...
on that entire page (which was last edited 2013-03-07 21:36:50)

I only saw 3 links that might help you Rick:

<quote>
Generic sound troubleshooting (last edited 2012-12-10 16:22:27)
https://help.ubuntu.com/community/SoundTroubleshooting

USB Sound Modem How-To (last edited 2011-05-07 15:47:55)
https://wiki.ubuntu.com/UbuntuHams/USBSoundModem
(mostly about ax25 which has nothing to do with WSJTX on Ubuntu)

and the Tigertronics link
https://wiki.ubuntu.com/SignaLink
which says:
"This page does not exist yet. You can create a new empty page, or use
one of the page templates."

so Rick I'd venture to say the only possible help found on that
https://wiki.ubuntu.com/UbuntuHams link that might help is the Generic
sound troubleshooting link which is almost 2 year old.

read that link for possible help and then when/if you still are lost,
ask again and hopefully someone will be able to help you better next time.

ah so, the last link on the https://wiki.ubuntu.com/UbuntuHams page,
I missed it when I stopped short at the Configuration & Troubleshooting
section, where the Generic Sound Card link was.

Good catch Ed, it's a shame we can't all be as good as you are ;-/

I had same problem- this worked for me-- (Also got to WSJTgroup) for more
recent info on this


Sam - thanks for the help!

Only difference for me is that input for Signalink is 13 12 ALSA pulse.
ALSA p148r does not show up on input list.

P148r is on output and is what I am set up.
Need to test xmit though.

Thanks Dan KC2STA

I had a similar problem, here was my post to [linuxhams] yahoo group

<quote>
I was having troubles with no RX when trying to us my SignaLink USB with
WSJT

when trying to use USB Audio CODEC: USB Audio (hw:3,0) for Audio In
I would get a popup window that says:
error in Sound in
"Port Audio says requested sound card format not supported"

and another popup window that says:
"Failed to start audio input stream"

John Nogatch the maintainer for the WSJTX package sent me the following
info:

==============================
<quote>
Are you starting wsjtx from a terminal window? Are you observing the
"...SetApproximateSampleRate..." message?

wsjtx tries to open the sound input device with sampleRate=48000. If
the device does not support that rate, then error messages are
produced. For example, if I try to use device hw:1,0 directly, then I
see these messages in the terminal window:

Expression 'SetApproximateSampleRate( pcm, hwParams, sr )' failed in
'src/hostapi/alsa/pa_linux_alsa.c', line: 1968
Expression 'PaAlsaStreamComponent_InitialConfigure( &self->capture,
inParams, self->primeBuffers, hwParamsCapture, &realSr )' failed in
'src/h
ostapi/alsa/pa_linux_alsa.c', line: 2643
Expression 'PaAlsaStream_Configure( stream, inputParameters,
outputParameters, sampleRate, framesPerBuffer, &inputLatency,
&outputLatency, &ho
stBufferSizeMode )' failed in 'src/hostapi/alsa/pa_linux_alsa.c', line:
2767

I was able to make this device work by creating ~/.asoundrc with
this entry in it, and then telling wsjtx to use device "p148k":
pcm.p148k {
type plug
slave {
pcm "hw:1,0"
format S16_LE
channels 1
rate 48000
}
}

Note that the entry is specific for audio device "hw:1,0". It creates
a new virtual audio device, based on hw:1,0 but supporting the desired
sample rate. You can see the id number of all audio devices by running
alsamixer and hitting function key F6. Use the hw number for your
particular device.

Version 1.2 of wsjtx will use QtAudio, which does support samplerate
conversion, so the .asoundrc file will not be needed.
</quote>
======================================

so I checked and saw the exact "...SetApproximateSampleRate..." message?
and then I created a .asoundrc file containing:

pcm.p148k {
type plug
slave {
pcm "hw:3,0"
format S16_LE
channels 1
rate 48000
}
}

saved it in my home directory ~/.asoundrc or /home/sam/.asoundrc

told WSJTX to use ALSA p148k for audio in

and now WSJTX is happy and starts with no errors and
I have control of both my TX & RX volumes levels
using the pots on the front of the SignaLink USB

this has also freed up my line in port to the sound card of my mother board
I had been using the Aux out of the SignaLink USB to the line in to get RX
signals to WSJTX.

Hello all

I am trying to set up wsjt-x on a Ubuntu 12.04 machine. Sound card is a
Signalink USB.

Program opens ok, but when I select and save the Signalink as the input
audio, the program crashes. If I select anything else for input, program
is happy.

I can set the Signalink as output card ok.

Any help would be appreciated!

Thanks Dan KC2STA

Thanks Dan, I feared the age of this 'fix' could cause confusion and be
obsolete, so I didn't post it since it speaks of Ubuntu 12 as well as
pre version WSJTX 1.2 We're now up to Ubuntu 14 and in 5 days V1.4 of WSJTX

I have no interest in this at all, but............

for TX I selected ..

11 2 ALSA SignaLink-USB

I did need to reboot.

All I wanted to do was try and help someone that was asking for help.

Thanks, I think, for the multiple responses to my query. The web page that
seemed to provide the info I need (buntu.com/UbuntuHams/USBSoundModem) is
unfortunately far beyond my capabilities as a newcomer to Linux-Ubuntu.
I've been able to get a number of things working including FlDigi, which
works fine with the USB Tigertronics SignaLink. I'll of course read through
the Wiki page again, but I'm not optimistic that I'll understand it
sufficiently to do what is necessary to get SignLink to work with WSJT.

Thanks

It has been quite a while since I’ve setup WSJT-X on Linux, but I remember that it wasn’t that difficult when using Pulse (it was a lot more difficult before Pulse audio).

I opened PAVUCONTROL (do you have that installed?) so I could see the Pulse Audio controls. Then I started WSJTX and it would appear in the Pavucontrol application. I did have to experiment with the precise audio selection in WSJTX, but it was all some form of Pulse audio support over the USB Audio Codec (may have had a different name; can’t recall for certain).

Again, it has been a while, and I’m doing this from memory, but it definitely can be done.
