TRANSCRIBER - Could not gain access to /dev/sound/dsp

Hello.
I am still with problems in transcriber using latest version ubuntu 20.04 lts.

I checked several forums all I tried doesn t work. Also, I am a trollmatic so you got to really explain things otherwise i won t understand.

I can see transcriber has a problem because the icon image is not displayed properly in the left size bar as it should.

I used transcriber previously in other ubuntu version and it ran perfectly well.

Now, the only think that helps is "padsp transcriber" but after the program blocks and I have to kill it.

The original file was wma, i used "audacity" to convert into ogg and when opening file:

Could not gain access to /dev/sound/dsp for writing.Could not gain access to /dev/sound/dsp for writing.

PLEASE, HELP!
