retropie sound card emu0202

[Heiser]

Hi guys. I have a sound card creative emu0202.
I have installed on raspberry KODI system where the card is working normally, and RETROPIE after using the commands of this post

card also works but I have a problem because the sound is interrupted.
In KODI it was the same when I had the settings automatically:
ALSA: E-MU 0202 | USB, Analog
after switching on:
ALSA: E-MU 0202 | USB, S / PDIF
sound in the end was normal.
I suppose that the same must be done in retropie but the question is how?
