[orca-list] Orca strange behavior in Ubuntu and RPi

[Vojtěch šmiro <vsmiro seznam cz>]

Hello,

I would like to inform you about some curious behavior of sound in 
Ubuntu Mate 20.04 in Raspberry Pi 4B 4 GB and 2 GB.

If you don't like workarounds, this is not for you, (smile).

I and my friend Libor have to use external sound card if we wanted to 
use Ubuntu. Libor found this curious behavior on Sunday. He allowed 
internal sound card and restarted computer. The system loaded loudly and 
sometimes volumed down a few percents, but not muted and Orca had sore 
throat. Libor turned Orca off and played some music with VLC for minute 
or two, better is two minutes in his 2 GB RPi. In my Raspberry Pi 4 GB 
it didn't work, but he found, due I have many profiles in Orca, I have 
to play music over four minutes. but at the end of the music, we turned 
Orca on again and we can use it without Orca's sore throats. It's really 
interresting. Why is this? During music play the sound is up, sometimes 
down like if you have problems with your cassette. But now Ubuntu is 
quicker and my RPi isn't so hot like with external sound card.

Best regards

Vojta.
