Hmm, when I put that in my default.pa, and set the profile to off for
my card - and restart pulse, speaker-test hangs. Other apps will just
not play sound. After closing everything and reopening, it seems to
Maybe I should reboot - other apps could be grabbing the soundcard
before pulse gets it?
I would NOT want to use dmix underneath pulse, right? Would probably
add a lot of latency.
Is it possible or a _good_ idea to move the LADSPA configuration to
run directly in Pulse instead of Alsa?
There is one example of that, but it's a bit hard to understand. Are
you aware of any better documentation? Looks like you split the main
channel into 4 mono channels, apply the ladspa filter to each, then
recombine. Is that the most sane way to do this?
Are the channel names what is listed in channel-map in pactl list?
