That's not a problem with ubuntu, but seems a problem with your compilation.
Show me please the output of the configure command

cd ~/zesarux/ ; git pull ; cd src ; ./configure

Try changing the audio driver. You have alsa, pulse and dsp

Set it by command line setting —ao or menú settings-audio-audio driver

settings-audio-audio driver

didn't see "Change audio driver" before. Thank you very much! Now it works
