Rein,

What are you setting as server string for pulseaudio in fldigi ?

If I set it to tcp:127.0.0.1:16560, then fldigi outputs to console:

E: trx_trx_receive_loop: PulseAudio error: Verbinding geweigerd
E: trx_trx_receive_loop: PulseAudio error: Verbinding geweigerd
E: trx_trx_receive_loop: PulseAudio error: Verbinding geweigerd
E: trx_trx_receive_loop: PulseAudio error: Verbinding geweigerd
E: trx_trx_receive_loop: PulseAudio error: Verbinding geweigerd
E: trx_trx_receive_loop: PulseAudio error: Verbinding geweigerd

and I do not see anything on the waterfall.

(note: I've uninstalled all my audio stuff and the alsa sound system as far as I can tell...
also I've compiled fldigi 3.21.83 and am running pskmail 1.7.0)

Fldigi will work with portaudio, but it has been the root cause of frequent crashes.
W1HkJ advises to use pulse audio for fldigi wherever possible.
jpskmail-2.0.30 can handle both port audio and pulse audio.
I personally use pulse audio on all my machines. On some machines
I need to keep pavucontrol running in the background when using audio in java.
I normally install pulse audio using synaptic, as I normally run Lubuntu.
But you can also use the .deb installer.

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

            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.

                    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.

                        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:

                            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
                            ~/.pskmail/configuration.xml file

                            3) and restarted pskmail:

                                just tested 2.0.30 on Lubuntu 14.04

                                Tested 2.0.30 with the K3.
                                * CAT PTT works with /dev/ttyUSB0.
                                woked only with an active USB hub
                                (with power).
                                * Audio works fine, you may have to
                                set the proper channels and levels
                                with pavucontrol
                                * Rig control works fine with CAT and
                                /dev/ttyUSB0
                                see attached pics for the settings....

                                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.

                                2) when starting pskmail 2.0.30 I get:

                                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 ...)
