setup issue

[Christine]

I followed the setup instructions, I removed pulseaudio from the pi, but the installer still stops saying I need to remove pulseaudio. It also said it couldn't find lxpanel. The file it wanted to update isn't on my pi, I created the file to make the installer continue.

The card does work though. I don't know if it works fully. Do I need to run the installer, or not, if the card produces sound?

Hi, good to know it works.

Can you please give the output of aplay -l and aplay -L ?

One test is to see if you can play a 1 channel audio file and an 8 channel audio file ? This would test that the "anyChannelCount" plugin is the default plugin. You could also check the contents of the file .asoundrc in your home directory.

thanks
Matt

Hi,

I have faced a similar problem with lxpanel. Thanks to this discussion, I created missing file (/home/pi/.config/lxpanel/LXDE-pi/panels/panel) with all parent directories and thus managed to complete setup script. I had no pulseadio installed.

The sound card cannot be found:

Code: Select all

 $ aplay -l
aplay: device_list:252: no soundcards found...

A snippet from dmesg:

Code: Select all

Any advices?

Your dmesg should say something about "cs42448" a few more times ... this is what I see :

Code: Select all

[    3.455840] cs42xx8 1-0048: found device, revision 4

Do you have anything else plugged into the GPIO (also can you please pm me ?)

thanks

I am now using Jack, I can use the Jack api from Java, if I get Jack to work with the octosound, I'm all set.
I can play an 8 channel wav file, the channels output the right sounds. So the octosound seems to work ok. My challenge now is to make Jack work with the octosound, then figure out how I control the 8 output channels from Java via Jack.

I found out how to make it all work. I use Jack to access the Octosound card, I use JnaJack to interface from Java to Jack. I described this in more detail here https://stackoverflow.com/questions/458 ... 2#46061522

I can now send audio individually to each of the eight speakers I have connected to the OctoSound.

Thanks for the update.

Even after my previous post, it toook me quite a while to get everything going. The issues were not in the card, but rather in debian/raspbian and in Jack and the interface with Jack (JnaJack). I have extended the stackoverflow post. I can now address every output port in the octosound card individually. You need to patch Jack2d, even if the links you find say you don't. The docs I found are from 2014, they were using a previous version of Debian. Using Jack from Java, you need to activate the ports in the card and keep the Jack ports open until you're done.
