hello noisy penguin lovers.
erm, firstly maybe i should post this to alsa user or something, but
maybe im lazy - im already on this list so i'll post here unless anyone
gets offended. ok?
im also slightly annoyed with myself for having to post this message,
because there seems to be various discussions about this in the archives
of various mailing lists but im still a bit confused. Ive also spent too
much time today fiddling around to keep quite about this one so here
(ive got a soundblaster 128 pci with the ens1371 chip)
when running :
# jackd -R -d alsa
i get the following message:
creating alsa driver ... default|1024|2|48000|swmon
You appear to be using the ALSA software "plug" layer, probably
a result of using the "default" ALSA device. This is less
efficient than it could be. Consider using a ~/.asoundrc file
to define a hardware audio device rather than using the plug layer
my ~/.asoundrc file reads as follows:
i thought the basic idea of .asoundrc was just to name pcm devices,
er...and then i thought jack would be able to find it??? maybe i assume
anyway, anyone know i run jackd so that it doesnt use the software
'plug' layer? What driver args do i need to use?
