Goodness, I'm so frustrated...
Finally I managed to get the LFE channel to show up as a pulseaudio sink.
Now I have all 6 (5.1) channels there, and last night I managed to get it
all started and watch a movie, and it sounded good. My Pianoteq didn't
work (notes played from the app, but not from the actual keyboard), but I
thought I would be able to figure that out soon. But then I came home
from work and now I'm stuck again. Can't get anything to work!! I don't
really know what I'm doing, so I spend hours trying different combinations,
but I'm not getting anywhere. Here are the pieces of my puzzle:
1. qjackctl and hdspmixer. I know I have to run hdspmixer to get driver
loaded for the RME 9652 card,
No? The driver gets loaded by hdsploader. hdspmixer sets mixer
defaults useful for hearing something, but you can do that
non-interactively using amixer. I have a hdspreset script looking like
#!/bin/sh
amixer -c 1 cset "iface=CARD,name=Precise Pointer" 1
# Inputs to HDSP Mixer
# ========================================================================
# Multiface analogue inputs 1-8 = amixer source channels 0-7
# Multiface ADAT inputs 1-8 = amixer source channels 16-23
# Multiface SPDIF input = amixer source channels 24-25
# alsa_pcm:playback_1-26 = amixer source channels 26-51
#
# Outputs from HDSP Mixer
# ========================================================================
# Multiface analogue outputs 1-8 = amixer destination channels 0-7
# Multiface ADAT outputs 1-8 = amixer destination channels 16-23
# Multiface SPDIF output = amixer destination channels 24-25
# Multiface line (headphone) output = amixer destination channels 26-27
#
# Mapping between Multiface inputs and alsa_pcm:capture channels
# ========================================================================
# Multiface analogue inputs 1-8 = capture_1-8
# Multiface ADAT inputs 1-8 = capture_9-16
# Multiface SPDIF input = capture_17-18
amixer -c 1 cset numid=5 26,0,65535
amixer -c 1 cset numid=5 27,1,65535
That would appear to put through the playback outputs 1 and 2 to analog
outputs 1 and 2.
Don't ask me about the Precise Pointer thing: at some point of time
jackd and pulseaudio needed _different_ settings in order to work
properly. Don't remember which was which or whether this is still the
case.
