Appreciated. though wiped my machine and happily did fresh minimalist
install again after much pulse and jack time. Lot of reasons and of
course pulse and jack are great. Simply, I need it manageable.
This can be done with just ALSA. Can't speak for the quality of
resultant sound though with aloop/multi/asym/dmix/dsnoop it can be
done. I would really ask now for help from a guru as I've been asking
for help for weeks and have tried everything though will keep trying.
Can someone please tell me what to change/add in the .asoundrc below.
I need to merge a 2nd stream INTO the microphone channel, i think,
during a skype/voip conversation. I have aloop driver installed and
working as well as 'almost' enough knowledge.
REALLY asking please.
