All,
It's not about skype, it's about jack, hydrogen, rackarack, sooperlooper, audacity, and a bunch of others. 

It was installing pavucontroll that blew the previous settings ...

Hi Jan , If you wish to run Skype ,..... it is Pulse Audio . To manipulate pulse audio volume level ,install pavucontrol 
It is in most repositories .   sudo apt-get install pavucontrol

    This is really bullshit. This has so screwed my setup that I have
    to reinstall the machine completely. Why use pulseaudio if alsa is
    standard amongst audio users on Linux ? Ever heard of jack ?

    All,

    A never ending story.

    I tried to go back to fldigi 3.21.74 (removed 3.21.83 by using
    make uninstall and installing thru apt-get) but to no avail.

    I remarked a slight change in behaviour compared to jpskmail
    2.0.30 however. When pressing "tune" in fldigi, the tranceiver
    very briefly goes into transmit, but inmediately stops. This
    points to a sound card config problem rather than a serial port
    problem.

    So it seems that this latest fldigi install has corrupted my
    sound card configuration. At fldigi startup, these messages look
    conspicious to me:

    Can anyone point me to the correct soundconfig (pulseaudio,
    alsa, or whatever)  for use with fldigi / pskmail ?

    All,

    After success with fldigi 3.21.74 and pskmail 1.5.29 I decided
    to drop jpskmail and go for fldigi 3.21.83 and pskmail 1.7.0

    installation of pskmail 1.7.0 is straightforward, i've just
    overwritten the 1.5 javapskmail.jar file.

    I dropped fldigi 1.5.29 thru synaptic (apt-get frontend), and
    did a full install from source as described in:
    https://fedorahosted.org/fldigi/wiki/Documentation/HOWTO/Mint_installation

    Everything starts fine, but again no ptt ...

    when pressing the tune button in fldigi, it outputs to the
    console a whole bunch of these lines:
    ALSA lib pcm.c:7843:(snd_pcm_recover) underrun occurred
    ALSA lib pcm.c:7843:(snd_pcm_recover) underrun occurred
    ALSA lib pcm.c:7843:(snd_pcm_recover) underrun occurred

    google is my friend, looking for that line gives me an
    interesting page:
    
http://tux-is-gaming.blogspot.be/2014/02/fixing-alsa-lib-pcmc7843sndpcmrecover.html

    this is clearly not an fldigi / pskmail problem, but rather a
    sound configuration problem. This has allways been a problem
    under linux, due to too many (competing) systems.

    But in the end my ptt does not go thru the sound card, it
    should go thru the usb / serial connection. So, as for the
    problem with jpskmail 2.0.30, I'm still suspecting the rxtx
    serial driver.

    ptt thru the cat interface is not an option as the cat
    interface is used for the antenna tuner
    ptt thru vox is not working either, vox does not work in digi
    mode on an ft817 . I've seen a workaround for this, but that
    involves soldering a resistor on the ft817's motherboard ...

    all idea's are welcome.

    Jan,

    IMHO you are wasting time.  Version 2.x is a dead end, at
    least for now. You better concentrate on pskmail 1.7.0 and
    fldigi 3.21.83 as Rein suggested.

    I hear SM0RWO-1 and/or OE5RTL, 9A1CRA regularly, but also
    could activate DL4OAH-1 on 80 or 40 Meter.

    All,

    Further testing:

    I've installed fldigi 3.21.74 (thru synaptic) and pskmail 1.5.29

    with fldigi I found out that /dev/ttyUSB0 had only 660 rights
    (so no r/w rights for others). I've set that to 666 and then
    no problem to receive AND transmit with fldigi and pskmail
    1.5.29 ! it's just that I do not hear any server, as usual :-(

    But !! the 666 rights on /dev/ttyUSB0 did not change a thing
    in the behaviour of jpskmail 2.0 (haven't tried 2.1 yet).
    Output when starting pskmail 2.0 is still:

    java -jar javapskmail.jar
    configuration.xml

        native lib Version = RXTX-2.2pre2
    port:/dev/ttyUSB0

    I would suggest to seriously test the usage of this newer
    rxtx library, and also to re-test the behaviour with
    different versions of ~/.pskmail/configuration.xml .

    3) I did not remove my old configuration.xml file in

    As this error appeard to be caused by a stale lock file, I
    removed ttyUSB0 lock file:
    rm /var/lock/LCK..ttyUSB0

    2) and restarted pskmail:
        same error remained. So I removed

        now UI appeared without settings,
    entered my settings (see screenshot - I'm using hardware PTT

    but the tranceiver is still not going into transmit ...

    Let me know if you still have problems... BTW, you can also
    do this with jPSKmail-1.7.0/fldigi,
    there you have 2 new modes (DominoEx 11 and 22). Use
    fldigi-3.21.83, which does not crash anymore...

    All,

    The radio is repaired and holliday is over, so I'm back to
    trying pskmail.

    My setup:
    - radio ft 817, so no vox in digi mode.
    - simple modem from intermar (can't find it on their site
    anymore)
    in pskmail ptt is set to hardware ptt using rts pin, ptt
    port is set to
    /dev/ttyUSB0.

    at javapskmail.Mainpskmailui.<init>(Mainpskmailui.java:994)

    and UI does not show up ...

    2) when starting pskmail 2.0.30 I get:
    java -jar /home/jan/pskmail21/javapskmail.jar

    But I do get into UI and I can receive signal. But whenever
    I try to
    tune or to send, I get this output on console:
    port:/dev/ttyUSB0
    port:/dev/ttyUSB0
    and radio does not switch to transmit. So I presume this
    rxtx version
    mismatch causes pskmail to not find the ptt ...

    I have downloaded rxtx-2.1.7.jar, but I cannot make pskmail
    work with
    this .jar . I put it in the jpskmail folder, in my .pskmail
    folder,
    tried to specify in in the java -cp command, but to no avail.

    How do I do this, or do you see another solution ?

    ( before I blew the radio, I got the system working with
    pskmail
    1.something and fldigi, and that setup has worked ...)
