Only one
instance needed. (And if not using JACK, other instances cannot
access the soundcard since Delta 1010LT (ice1712) is single access card)
Even if you use the dshare pcm slave plugin?
dshare and JACK are conseptually the same: you can acces them from
multiple programs but still only one snd_pcm_open is allowed and that's
done from dshare or JACK
