Running Ubuntu 13.04 AMD Athlon II X2 64 bit os, 4gigs of RAM, Audacity
2.03. When imorting a tape, Audacity would stop recording at diferent
points on the tape. I was using the playthtough feature and noticed an
unusual sounding noise, hi pitched , like a digital tone and recording
then stoped.

Well, something like that. The applets and utilities supplied by

Thanks Per for bringing this issue to upstream. Is it correct that this

I posted to the Audacity forum and got some interesting feedback:

Apparently, the problem is partially fixed on the trunk, i.e., the xrun-
recovery code has been improved so that recording will not
@David: you're welcome! Interesting indeed. Looks like there is some
sort of consensus on the Audacity forums that software play-through just
cannot work under Linux. Hope that can change now.

@Bdrung, would you mind bringing this upstream for discussion? I'm quite
busy currently.

Now I think I know why there are overruns and underruns: there is
something wrong with the latencies.
The attached patch disables the special handling of the playthrough case
and uses the user-settable latency for both capture and playback. The
patch also contains a few diagnostic output

I think I have identified where the problem lies: in the underrun
handling of the playback stream. I don't know what causes the underrun,
but the recovery mechanism does not have the desired effect, so both
capture and playback remain frozen.

I on ubuntu 10.10 with audacity 1.3.13 alpha Nov 9 2010 (from pkg:
1.3.12+svn201011090133+r6466-0~maverick1).
i test ALL the suggestions, but nothing not work (the pkg for lenny of
course work but is detour, it's not really fix it... and also it's very
old audacity :)
In the beta version of Audacity, this only happens to me in overdub. In
other words, I can record one track, but as soon as I start recording
another one it doesn't work. I have to turn off overdub for it to work,
but then I can't listen to the previous track while recording the new
one.

Hi,
As suggested by others, I got rid of this bug in Kubuntu Karmic
(Audacity 1.3.9, no PulseAudio, no Jackd) by changing the default sample
frequency to 48 KHz in Preferences - Quality.

I'm having the same issue on Lucid (10.04). Record stops after a second
or so. I don't use PulseAudio (my ALSA configuration is quite big and I
don't want to switch to PA, yet). Disabling 'software playthrough' helps
but in my case I can't get any sound recording while recording.

I've get rid of the problem of no sound recording - I've choose invalid source
for input. Now it records sound properly, but without disabled 'software
playthrough' option as suggested in this bug report.
I've got no jackd or other sound server, pulseaudio removed, keept just ALSA.

Same thing for me. I do not have jackd installed.
It's quite funny because on this new lucid install I couldn't believe it but
monitoring worked without my tweaking anything! I was amazed, as my prior
experiences with Audacity in linux have forced me (a very avid gnu/linux user)
to record in
Seems jackd may be involved.

I could get this feature to work in Karmic by using (hw0,0) as my
playback device. Sometimes the choice wouldn't be there and I would have
to try restarting Audacity (while closing firefox and various programs).
In Lucid Lynx, no matter what I do.. I cannot get (hw0,0) to show up as

On another note.. In Lucid Lynx, I can get software playthrough to work
when I use PulseAudio to record and not ALSA. I do, however, have to
manually select the record device in alsamixer because it is not listed
in the gnome sound manager.

I have the same problem using Jaunty. I have tried all the suggestions
and increasing the sample rate to 48khz does work. changing latency does
have varying effects - higher latency recording stops altogether and
lower latency results in no recording at all. This appears to only
effect recording
After I set the Latency Correction in Audacity Preferences/Audio I/O
to 0 milliseconds, I have had no further problems with recording.
Perhaps the problem is in the latency correction.

I am a new Audacity user, and have similar recording problems. Ubuntu
9.04, Audacity 1.3., Athlon 1500+, Audigy sound card.
Many times, recording will stop after a fraction of a second, and
sometimes a dialog box will pop up warning about latency problems
(sorry, I can't reproduce it right now)
Karmic also effected with this problem but pulse audio had to be
uninstalled to get sound working for me. using the lenny version of
audacity mentioned in earlier posts allows recording to work.
with the pulse problems i've had my system isn't clean enough to confirm
its a problem with audacity.
I'm having the same problem, without software playthrough enabled. It
stops recording at about 0.2 seconds, but the bar keeps moving and the
monitor keeps working. It works at 22050hz, but nothing higher (contrary
to other reports that seem to have a minimum rather than a maximum).

Not sure if this information is useful but... I continued to play with
Audacity and Pulseaudio. I turned off Software Playthrough and that
did not fix the problem. It still only worked at 96Khz and 48Khz. I
installed PulseAudio Device Chooser. I took a look at the sinks and

I don't know if it is the same thing but when I try to record, the red
line moves across to 1 second, maybe 2, and stops. I am new to Audacity
(and to Linux, in fact) and what puzzled me was that, when I used it for

The way I 'fixed' this bug, is to set the Default Sample Rate to 48000

at least we know what's causing the problem.

also, the same behavior occurs when just monitoring the input. i.e. the

is it the same bug? can you verify if recording works with software

I have the exact same problem. Don't know how to tell what card I have

Btw, everything was working fine until I upgraded to Ubuntu 9.04. When I
upgraded everything was slow but enabling UXA made it speed up. The only
thing not working now is Audacity with software play-through. I can get
it to sort of work by playing with the input and output devices in
Audacity, but
I have tried compiling the latest Audacity CVS (its in my PPA), but the
problem still occurs. There is also a forum topic on Audacity's forum
about this, but there isn't any solution there. I tried this same thing

doesn't happen
I just checked, and it produces no output in the console when this
occurs.
