unixcw in Ubuntu 14.10 is available in version 3.0.2. I was able to 
reproduce the problem with this version: sound became distorted after 
less than a minute.

I was not able to reproduce the problem with unixcw 3.4.1 compiled from 
sources.

I think that the problem stems from the fact, that unixcw 3.0.2 does not 
support PulseAudio directly, only through ALSA (unixcw -> ALSA -> 
PulseAudio -> speakers). Direct support for PulseAudio in unixcw has 
been added later.

I would recommend installing unixcw 3.4.1 to avoid this kind of problem.
An alternative is to uninstall PulseAudio :)

Best regards,
Kamil

This week I will try to run unixcw 3.4.0 and unixcw 3.4.1 on Ubuntu 
14.10 and see if I can reproduce any problems with audio.

Hello Andy,

I'm sorry for late reply, for some reason I never got a notification 
from the mailing list.

I'm not handling packaging of unixcw for any distribution, so I cannot 
tell which package version is / will be available for Ubuntu 13.10.

Unfortunately I don't know what could be the cause of your problem with 
dahs, perhaps you could try the most recent version of unixcw (3.4.1) - 
maybe the problem is fixed there.

Best regards,
Kamil

cw defaults to ALSA because it doesn't detect PulseAudio server, or it 
cannot access it. I don't know why exactly that happens on your system. 
Please double check that you have the PulseAudio server running and that 
other applications that you start can use it.

I just checked the behaviour of cwgen in 3.0.2 and in 3.4.0. In both 
cases the behaviour is the same: cwgen generates a group of characters 
(as specified by command line, or with default settings). The man page 
for cwgen mentions that *groups* of characters are generated.

In you script you use this set of commands:

$ cwgen | cw

cwgen has to generate all the characters at once. There is no way that 
cw can tell the cwgen "generate me next character". What you describe is 
the intended behaviour of cwgen.

This is also intended behaviour. From man page:
    -x, --limit
        Specifies an upper limit on the number of characters printed.


Please let me know if you have any other questions.

Kamil

[Unixcw-user] weird problem

[zebul666 <zeb...@ho...>]

hello,

I was using unicw 3.0.2 in  ubuntu 14.10, but the sound what horrible
and distorted.

So I decided to try the latest uniwcw  3.4 as there was all the needed
file to make a package for ubuntu/debian.

l wuse the little joined script.

and it does not detect correctly the pulseaudio device. it seems to
default to alsa... weird.
If I force the pulse audio output in cw with -s p then I got no sound
and it stops.

when I use my script, cwgen spits out many character at once on
screen, whereas it didn't do that before with 3.0.2, just once at a
time.

if I use the -x 1 switch, it stops after one character which may be
the intended behavior but not clear to me from the man page.

at least the sound is good.

[Unixcw-user] Unixcw 3.3 for Ubuntu 13.10?

[Andy H. <an...@ga...>]

Is there a unixcw 3.3 for Ubuntu 13.10? The current version is 3.0.2. The xcwcp program
only plays back at about 5 WPM.

I compiled the latest from GIT and installed it locally. This version seems to work at the
right WPM, but it only send dits, no dahs.

Any ideas how to make this work?

73,
