lynx.cfg - mime types - viewer for text terminal audio player mpg123

Dear lynx experts,

I want to play mp3 files with the external text terminal player mpg123.
This does no longer wirk with my change from Debian to Ubuntu.

I'm using:
lynx 2.9.0dev.10 - Ubuntu 22.04.3 LTS

Extract from .lynx.cfg:
# MIME types and viewers!
#
SUFFIX:.mp3:audio/mpeg
VIEWER:audio/mpeg:mpg123 -v %s
---

Problem: vlc is started instead of mpg123.
It seems that the mime type definition in .lynx.cfg is ignored or
overwritten. Adding :NON_XWINDOWS or :XWINDOWS at the end of the
viewer definition has no effect.
In best case I'd like to start mpg123 independed from the setting of the
display environment variable.

I found some discussion on this issue in the lynx-dev mailing list archive
end 2018 but no solutiton.

Any hint is very welcome

Best, Klaus
