[Ardour-Users] Virtual "merge" device doesn't work following steps on the wiki

Dear all.

I've followed the instructions in the wiki[1] to get a personalized
virtual hybrid audio device in such a way that I can use the INs and
OUTs of my internal and external cards.

I copied the specification example for asoundrc file and just made
some little changes to adapt it to my preferences: I refer to my
external sound card by name, and I put its channels first in order
instead of the internal card as is in the example.

I put my .asoundrc in place and restarted the system but no merge
device appeared on QJactl configuration. At the end of this mail is my
.asoundrc file[2].

I think I followed every step as indicated, but maybe I missed something.

BTW, there are two lines in the example that don't ';' at the end of
the line, and checking other examples it seems it is mandatory. Just
in case, I tested my configuration as the example and with ';' on
every line, but no luck.

Thanks in advance.
