How to setup and test

Including ls below just to show the .wav file exists and in case I'm making a dumb mistake.

Oh - your .asoundrc or /etc/asound.conf file are declaring the plugin anyChannelCount - this plugin is for the octor device. Are you using the octo device or the stereo sound card ?

[terry1769]

Stereo. Guess I'll go back through the setup again.

[terry1769]

Thanks! I deleted .asoundrc and reinstalled. It appears to be working now.

Great news !

Tengo instalado el sistema operativo osmc y no consigo de ninguna manera poder instalar la tarjeta de audio audioinjector.Alguien tiene idea de como hacerlo?

[flatmax]

Can you link to the osmc operating system ?

thanks

Very excited about this board, and slugging through the last part of the install. I can play though the output channels, but get no joy from any input options. All testing and ALSC settings as you described. Can it be related to the dmesg message?

I'm prepared to send more data if this is not a clue.

Good news! Apparently the install went fine, but the soundcard input is barely responsive to some low signals. I was using mp3 playing from a cell phone at max output, but it was barely perceptible at max gain. Soon as I switched to a laptop source, it got into usable range. Balancing signals from a source playing on VLC on the RPi combined with inputs from external sources is tricky. Any suggestions on source balancing?

My goal is to use this RPi for internet radio streaming via Icecast. Very glad that I am not stuck on the card configuration stage and can move toward streaming functionality.

Hi, I have set both the octo and stereo cards up only to get audio out of one channel. I have used multiple pi's to check if it is my equipment. not sure what to do can anyone help?
