Thanks so much!

At the same time I read your email, we received this email on the netbsd-users list, with
fundamentaly the same instructions:

https://mail-index.netbsd.org/netbsd-users/2026/11/10/msg035264.html

I have succeded with the earphones but not with the speaker using the
/dev/pad.

Perhaps the speaker do not support the same A2DP audio playback. Who
knows....

I will be investigating it further, no more free time today.

Many thanks.
Ramiro.
