ok

could that have been covered somehow by a workaround in pa-4 ?

I shall try to get back the entry with all the profiles to check this.
Also, don't know if it is related, after a while, when using the "Analog Output
- Built-in Audio" with the only "Analog Surround 2.1 Output" profile available,
sounds gets gibberish after a while.
I have to stop the player and start it again to get sound back to normal. Other
sound like the ones from speaker tests are good while this problem is occuring
in another player.
