Octo on 2018-11-13 raspbian stretch lite not working

[jochen.richert]

Hello

I just received my octo cards and would like to use the inputs on my octocard to capture sounds, but do not get it running.

Here's my config:
Raspberry Pi Model B Plus Rev 1.2
PRETTY_NAME="Raspbian GNU/Linux 9 (stretch)"
NAME="Raspbian GNU/Linux"
VERSION_ID="9"
VERSION="9 (stretch)"
ID=raspbian
ID_LIKE=debian
HOME_URL="http://www.raspbian.org/"
SUPPORT_URL="http://www.raspbian.org/RaspbianForums"
BUG_REPORT_URL="http://www.raspbian.org/RaspbianBugs"

I can't use the sudo dpkg -i Downloads/audioinjector.octo.setup_0.3_all.deb command so I gone the manual way via Firmware Upgrade which was running fine.

Also the changes in the /boot/config.txt are done.
# Uncomment some or all of these to enable the optional hardware interfaces
#dtparam=i2c_arm=on
#dtparam=i2s=on
#dtparam=spi=on

# Uncomment this to enable the lirc-rpi module
#dtoverlay=lirc-rpi

# Additional overlays and parameters are documented /boot/overlays/README
# Enable audio (loads snd_bcm2835)
#dtparam=audio=on
# enable the AudioInjector.net sound card
dtoverlay=audioinjector-addons


pi@vlf-01-pi:~ $ dmesg | grep audio
[ 15.243097] audioinjector-octo soc ASoC: CPU DAI (null) not registered - will retry
[ 15.243133] audioinjector-octo soc snd_soc_register_card failed (-517)

[ 21.996351] audioinjector-octo soc cs42448 <-> 20203000.i2s mapping ok

After that I run all these commands
sudo modprobe -r snd_soc_audioinjector_octo_soundcard
sudo modprobe -r snd_soc_cs42xx8_i2c
sudo modprobe -r snd_soc_cs42xx8
sudo modprobe snd_soc_cs42xx8
sudo modprobe snd_soc_cs42xx8_i2c
sudo modprobe snd_soc_audioinjector_octo_soundcard

No error message, just this line added to DMESG

[ 107.347648] audioinjector-octo soc cs42448 <-> 20203000.i2s mapping ok
pi@vlf-01-pi:~ $

Any idea what I can further do?

Many thanks

Hi there,

I am currently remote - with no Octo. I will check this problem later this month and get back to you.
In the mean time, you may want to downgrade your kernel (using rpi-update) to a slightly older version since before this problem showed up.
rpi-update VERSION
Where VERSION is the git commit number from here :
https://github.com/Hexxeh/rpi-firmware/commits/master

For example this would take it back around one month ago :
rpi-update eefe4b161f5e9730183c8dc1605e14c85b15cf51

thanks
Matt

I have the same issue as the OP but I used the automatic installation deb. The only error I saw when doing the automatic install was:

Code: Select all

lxpanel's volume plugin is disfunctional, disabling it
sed: can't read /home/pi/.config/lxpanel/LXDE-pi/panels/panel: No such file or directory
dpkg: error processing package audioinjector.octo.setup (--install):
 subprocess installed post-installation script returned error exit status 2
Errors were encountered while processing:
 audioinjector.octo.setup

..which I attribute the fact that I am running Stretch Lite which has no desktop and therefore no lxpanel. So no worries.
Then I did what jochen did:

Code: Select all

pi@democase01:~ $ dmesg | grep audio
[    7.281494] audioinjector-octo soc:sound: ASoC: CODEC DAI cs42448 not registered - will retry
[    7.281516] audioinjector-octo soc:sound: snd_soc_register_card failed (-517)
[    8.851407] audioinjector-octo soc:sound: ASoC: CODEC DAI cs42448 not registered - will retry
[    8.851419] audioinjector-octo soc:sound: snd_soc_register_card failed (-517)

Very similar result.
I took your advice and rolled back the kernel per your suggestion (about a month ago). No change in behavior.
I ran all the sudo modprobe commands per your suggestion and re-ran dmesg | grep audio:

Code: Select all

pi@democase01:~ $ sudo modprobe -r snd_soc_audioinjector_octo_soundcard
pi@democase01:~ $ sudo modprobe -r snd_soc_audioinjector_octo_soundcard
pi@democase01:~ $ sudo modprobe -r snd_soc_cs42xx8_i2c
pi@democase01:~ $ sudo modprobe -r snd_soc_cs42xx8
pi@democase01:~ $ sudo modprobe snd_soc_cs42xx8
pi@democase01:~ $ sudo modprobe snd_soc_cs42xx8_i2c
pi@democase01:~ $ sudo modprobe snd_soc_audioinjector_octo_soundcard
pi@democase01:~ $ dmesg | grep audio
[    7.281494] audioinjector-octo soc:sound: ASoC: CODEC DAI cs42448 not registered - will retry
[    7.281516] audioinjector-octo soc:sound: snd_soc_register_card failed (-517)
[    8.851407] audioinjector-octo soc:sound: ASoC: CODEC DAI cs42448 not registered - will retry
[    8.851419] audioinjector-octo soc:sound: snd_soc_register_card failed (-517)
[  786.214671] audioinjector-octo soc:sound: cs42448 <-> 3f203000.i2s mapping ok

So, no change, same results as jochen.

Just for grins I updated to the latest kernel release (4.14.94) with no change.
If you'd like to move this to github, that's fine, I can do that.
This is part of a project for work not play so I hope we can get moving forward quickly.
Thanks,

After posting the above, I went through several power cycles (orderly shutdown & restart) as I mounted the Octo to a insulating baseplate. Seeing as how there were conflicting indications about what was loaded/recognized and not, i tried running speaker-test, reasoning that if there was an error, I'd know things weren't recognized/loaded. Speaker-test ran without error. I hooked up a scope and sure enough, I got sinewaves on the two outputs I checked. And no more errors in dmesg:

Code: Select all

pi@democase01:~ $ dmesg | grep audio
[    7.084256] audioinjector-octo soc:sound: cs42448 <-> 3f203000.i2s mapping ok
pi@democase01:~ $ uname -a
Linux democase01 4.14.94-v7+ #1193 SMP Tue Jan 22 15:34:30 GMT 2019 armv7l GNU/Linux

So this is running with the kernel version shown above.

1) I will investigate more thoroughly and report on whether the channels change around -- this would be a KO for my project.
2) I am disappointed by the lack of documentation of this device. I cannot find anything that shows me which RCA jack is which output (or input). If I am missing something, I apologize, but point me to the documents please.
3) My project involves using GPIO pins to change the sounds produced. Which GPIO pins should NOT be used?
4) Are there preferred sample rates for audio playback?
5) My goal is to generate sinewaves on the fly but I will use pygame to get started. I will report back on this as well.

Hi Jeff

Thanks for all your investigation and work. I still have the error, but the MIC input seems to be working for me. Due to the snow situation I can not use my setup in the moment to do further investigation and testing.
I am using card for VLF or Spherics reception and analyzing. Therefore I am using a special SW called vlftools from abelian.org.
With the SW and a tone generator, I was able to inject an audio signal and identify the single channels in the sw.
So I can tell you the MIC in Ports are named as followed.
2 4 6
1 3 5
as seen straight to the plugs. So logically for the output, it should be the same.
Hope, this helps you a bit.

Cheers
Jochen

Hi again I tried not to switch off the battries but the aircraft still went off after some time...what am i doing wrong? Sorry to bother you
