Comment (by RüGi):

 Just installed 'ffmpeg version N-111259-g4aa1a42a91-20230623' and this
 error still occurs.

 There may be good reasons why it is not yet fixed, but then it is very
 strange for me that there is no comment or explanation, why it is not
 fixed.

 I wonder why libopus does not know how to deal with channel_layout
 5.1(side), since it is quite common in German DVB-T2 (digital terrestrial
 TV).

 A comment of some 'wise' (wo)men would be appreciated!

 P.S. For now, I can live with the solution form 'comment:11 by Peter
 White' (using
 {{{
 af aformat=channel_layouts="7.1|5.1|stereo
 }}}
 , but it is still an open question to me.
 Thanks
