I am trying to get FMOD (low level API) working on Ubuntu 13.04. All other applications use my default settings and play appropriately, but FMOD seems to be choosing my HDMI output as the default device. I can manually switch to the Built-In Analog device with FMOD, and everything works fine when I do that (using the “multiple systems” example code). But how is FMOD getting a different default device than every other application?

The HDMI Audio device is, in fact, the first one that comes up on any list of my devices (pacmd, etc.) but it’s strange that all other audio applications don’t exhibit the same behavior as FMOD.

EDIT:

It looks like FMOD is assuming that the PulseAudio API will return the default device first, which I believe is not the case for you. Can you provide the output from the following:

pacmd list-sinks

Also the TTY output from the logging version of FMOD.

If the output is as I expect, this will need a code patch on our side to fix.

    Thanks for the response. I added the info to the original question.
  • Mathew Block
    Thanks for the info, the output is as I expected. I will need to fix this for a coming release. I'll update this post when the work is complete.
