Hi!
After installing Audacity, my headphones stopped working.
If I plug them into the headphone jack, the loudspeaker turns off, but no sound comes out of the headphones.
Kindly help.
Thanks a lot.
If you have not tried already, install the application pulse audio volume control (pavucontrol) and check to ensure headphones are selected in that control app when plugged in. Also check to ensure they are not muted.
Thanks for the reply.
I’ve done that already.
pavucontrol shows that it switches to the headphones when plugged in and they aren’t muted, but I still can’t hear anything (my hearing is fine 
).
In pavucontrol Configuration tab, change the Profile to Off, then back to a good setting (Analog Stereo Duplex for my laptop). I have to do this occasionally to get sound after the machine resumes from sleep.
If after trying all the above recommended in this thread, if still ‘no joy’ then I believe it could be necessary to delve into this a lot deeper (and obviously I assume headphones function perfectly based on other testing you have done).
To provide more information, with headphones plugged in, and your openSUSE install configured as best as you believe possible (to work with headphones (after the audacity issue)) , as a regular user, open an xterm or konsole, and with regular user permissions send the following command to launch a diagnostic script (the idea being the diagnostic script might give an idea as to where problem is located):
/usr/sbin/alsa-info.sh
when prompted, select the “UPLOAD/SHARE” option. When the script completes it will put something like this in the konsole/xterm:

Please inform the person helping you.
Post the " http://alsa-project.org/db/?f=somenunmber" here, and we can take a look at it to see if it yields any clues as to what the problem may be.
… note if you have headphones working BEFORE running audacity, but they don’t work AFTER running audacity, you could also run the diagnostic script twice … once when the headphones work, and once when the headphones don’t work, and then compare the output of the scripts … as that may point to a difference indicating the issue.
