asound.conf for Matrix Voice

[nodered]

I noticed the new .asoundrc file to be used with the kernel modules at https://github.com/matrix-io/matrixio-kernel-modules/blob/master/misc/asoundrc ...Do you have a new /etc/asound.conf as well?

Just saw a comment in the forums...no need for the asound.conf...?

Hello @nodered , Thank You for your feedback. Yes, we are working on a new release and it will fix this issue. I will let you know when we complete it.

I made an image today with raspbian stretch light, the kernel modules, sox and snowboy. It’s just a start but something like this might make it faster/easier for people to get going. I think they call it ‘Onboarding’ now. It’s only 2GB so it’s quick download and burn.

I am now just using /etc/asound.conf and this conf is working for me. Any ideas on why mmap_emul would be more stable?

pcm.!default { type asym capture.pcm "mic" playback.pcm "speaker" }

pcm.mic { type softvol

min_dB -1.0 max_dB 50.0

slave { pcm "mmap0" } control { name "MicArray Master" card 0 } }

pcm.speaker { type plug slave { pcm "hw:0,0" } } pcm.mmap0 { type mmap_emul slave { pcm "hw:2,0" } }

Hello,

We remove the asound.conf in the matrix-creator-init package. Now, we are working on the Debian package for the kernel modules.

Meanwhile, you could use: https://github.com/matrix-io/matrixio-kernel-modules/blob/master/misc/asound.conf

Your image works great, no ambient distorted noise. I will use this as a base, many thanks

Just so that you know, the kernel modules in that image do not work with pulseaudio.

I have used it to install Snips (https://snips.ai/), so far working fine. There was an update in the kernel modules, so I will try and install those with a fresh strecth install as well
