#1

When I install Genie-Client on a RPi4, i can’t get the echo source/sink modules to load using default.pa,
I get the log error - Master source not found/Failed to load module “module-echo-cancel …”

If I load the module manually it works fine

#2

Did you add the “Load Modules…” lines to /etc/pulse/default.pa?

If not please look at the instruction at Installing a Genie Client on a Raspberry Pi | Genie Wiki This is hardware based so make sure to chose the right lines.

#3

Yep - that was what I meant - I added the lines into /etc/pulse/default.pa but if I look at the log it says Master source not found/Failed to load module “module-echo-cancel …”

Loading manually works fine

#4

What is the output of:

  • pacmd list-sources
  • pacmd list-sink-inputs

What are the lines you added to /etc/pulse/default.pa?

How are you loading it manually?

#5

Hi

Sorry I did not get a notification that your replied. In the future please use the code tags using the </> button on the editor so that formatting is retained. It makes it a lot easier to read.

I think your /etc/pulse/default.pa is wrong. aec_method should be speex. This is what I have working on my RPi4.
