How to troubleshoot recording stops after five minutes

[LNordin]

I have a problem where audacity will stop recording after 5 or 6 minutes.
I've read through the FAQ but haven't seen anything that applies to me.

The directory configured for temporary files has 7 GB of available space.

Is there a log to see what error occurred that stopped the recording?
I looked in Help > Diagnostics > Show Log but this doesn't have any errors.

I'm running Kubuntu 18.04.4 and Audacity v2.2.1.

What is your recording device?

[LNordin]

It is audio line in on a Dell PC. My choices are "default", "pulse" or "HDA Intel PCH: ALC3220 Analog (hw: 1,0)". My only choice for audio host is ALSA.
I just tried specifying HDA Intel but when I try to record most of the time it doesn't start.
I did notice that when I went to change the volume on KDE mixer that the recording stopped.

To fill in more standard information, I installed Ubuntu's version of Audacity.

My choices are "default", "pulse" or "HDA Intel PCH: ALC3220 Analog (hw: 1,0)"

Is there no "(hw: 0,0)" option?

If you shut down all audio applications,
then kill the KDE mixer,
then run:

Code: Select all

pulseaudio -k

and then start Audacity,
do you get a "(hw: 0,0)" option?

[LNordin]

No, there is no "(hw: 0,0)" option

Couldn't find a kmix process to kill.
Tried killing pulseaudio (pulseaudio -k) but it kept restarting.

What do you get from the command

Code: Select all

aplay -l

(that's a lower case "L" at the end)

aplay -l

From your "aplay -l"

Code: Select all

card 0: HDMI ...
card 1: PCH

Your default device is the HDMI device. Do you use HDMI audio? Do you use HDMI audio as your default audio out?

Have you customised your audio system in some way?

> Your default device is the HDMI device. Do you use HDMI audio? Do you use HDMI audio as your default audio out?

I don't use HDMI audio. The only connection is the analog line out (on of the back the PC) out to speakers and analog mic in (on the front of the PC).
My monitor connection is currently VGA but otherwise I use DisplayPort (which I think is video only).

> Have you customised your audio system in some way?

No. I don't think so. How can I tell?
