Hello,
I'm using Arch Linux (AArch64) for the first time on a Raspberry Pi 4. I
need to use HDMI sound and the first HDMI port on the pi is card 0. If I
try to use aplay to play a sound file it prints:
aplay: set_params:1343: Sample format non available
Available formats:
- IEC958_SUBFRAME_LE
I find that I can play audio through HDMI by specifying the sample
format. eg.
aplay -D iec958 mysound.wav
What I'm stuck with is trying to configure ALSA to make this
specification. I've tried the following in my ~/.asoundrc
pcm.!default {
       type plug
       slave {
             pcm "hw:0,0"
             format IEC958_SUBFRAME_LE
}
}
While this produces no Alsa syntax errors when I use aplay, it still
won't play the audio and prints:
Playing WAVE 'wav48k.wav' : Signed 16 bit Little Endian, Rate 48000 Hz,
Stereo
aplay: set_params:1343: Sample format non available
Available formats:
- IEC958_SUBFRAME_LE
Can anyone please help?
Thanks,
Iain

Hi LAU,
As we're entering a 'tighter' lock-down in my area this week I will need
to attend online music lessons (bass). The suggested tool is zoom with
'original sound' option selected, but it seems this is not available on
Linux (nor in a web (chrome?) client) [1].
In the past setting the 'noise reduction' (or maybe it's echo
cancellation) to low seemed to work OK, but I'm wondering if anyone
knows of any work-arounds.
Or any other platform (Discord seems to use Opus which sounds promising).
The one used for the last LAC seemed also quite nice, but I guess that's
not free (as in 'gratis')? As zoom is the tool selected by the music
school it should also be something relatively hassle-free for the
teacher and cross-platform (i.e. assume they will not be on Linux, so no
funky stuff like having to install a Mumble server etc. :-| ... Although
the offers on mumble.com seem quite reasonable, but has anyone used it
for music?)
I _am_ already able to set-up e.g. my Zoom H5 (the device not the
software) or usb audio interface via JACK to have a decent mic/input at
the source and then pulseaudio-jack sink for audio I/O with these apps
(I actually helped my son do remote drum lessons which included piping
smplayer via jack to him locally and his teacher as well as the e-drum
line out with JACK).
But of course there's no much point in having decent quality at the
source if the software is doing funky stuff like noise reduction and
echo cancellation at the source :-|
Any suggestion welcome.
Lorenzo.

there's more to it. :)
Instruments and plugins: Fluidsynth (electric bass), setBfree, Csound (FX,
shimmer reverb, vocoder), LinuxSampler (Csound FX, electric pianos), Yoshimi
(guitars, piano layer). Hardware: Prophet 12 (accents and strings), MiniBrute
2s (more synth accents), Behringer Neutron (synth bass, drum processing),
Rolanbd JV-1080 (basic drums).
Plugins: Fons' 4-band parametric filter (EQ), g2verb, zita-reverb (I think),
TAP TubeWarmth, stereo echo, CAPS 2x2 plate, amp and speaker models, guitarix
amp, SWH L/C/R delay, Invada Studio Compressor and possibly more.
Feedback as ever is welcome. :)

Hello!
We know that hosts such as Ardour are able to control the
parameters of LV2, LADSPA, VST, etc, plugins using MIDI CCs and
possibly other automation control signals.
Is there a (free, open source) plugin out there that allows for
controlling the parameters of a plugin from another plugin? I
realize that question's a bit nebulous. I'd like to, for example,
have a plugin that exposes a MIDI input. When a NOTE ON is received on
that input, it sets the value of a parameter in a different plugin
to a given value, and when a corresponding NOTE OFF is received,
it sets the value back to something else. Similar actions could
be performed from audio signals too, with a bit of math.
Ideally I'd like to set up a pile of plugins inside Carla and route
control signals between them in various ways like this. Some plugins
explicitly expose inputs that allow for control like this, but most
don't.
I've had a look for plugins that can achieve this kind of general
control, but the search terms are so generic that it's a tough thing to
search for. It may not even be possible.
Anyone know of anything?

Some years ago I played a short riff on one of of the LAC workshops. I don't
remember what particular feature of Yoshimi I was demonstrating, but I do
remember the piece well, and always wanted to expand it to to a full length
tune. Well here it is:

or

The original melody? That's the 'chorus'. I hope you like it.

Say you have a poem and I have a tune.
Exchange them and we can both have a poem, a tune, and a song.
Hey hey,
I did write and record change when I was about 17 or 18 and wanted to
re-record it for a while now:

And for OGG download:

The lyrics had to be rewritten entirely, though kept in the same style,
register and intention of the original. The main sound was a Roland JV_1080
patch called Raggatronic. I still have that patch, but in this recording I
used a copy I made on another virtual analogue synth.
Another change is the Yoshimi choir, which I certainly didn't have. It used to
be another Roland sound from an expansion board, which I don't have. I first
though of mixing other choir sounds on that module, but then layered the
Yoshimi choir with another hardware instrument. It's a beautiful synth choir,
with or without the other hardware layer! Thanks Will!
Best wishes,
Jeanette
