BTW Audio DSP add-on should be working in latest build. Some info here.
I believe "Audio DSP Basic Processor" and "Free Surround Processor" should work, but not "Biquad filters" yet.
Make sure omxplayer and passthrough are disabled. Enable in system/audio settings, and you can configure the add-on from audio OSD when playing a video.
You may need to enable the add-ons in Add-on browser/My Add-ons/Audio DSP.

I'll include the ADSP addons in the next build (#0620) but if at all possible I'd really like to avoid discussing ADSP-related issues in this thread. I've asked @wisler how he wants to handle this - a general "Bug reports" thread worked well for Estuary so could work well for ADSP. Alternatively, individual "Bug" threads could be started in the Audio DSP sub-forum.

I've found a way to crash Kodi using the ADSP add-ons, I'll report it here until we know how @wisler wants similar reports handled in future:

1. Enable "Audio DSP Basic Processor" and "Free Surround Processor" Audio DSP add-ons
2. Settings > Audio - enable audio DSP processing, then in Audio DSP manager enable "Speaker correction" post-processing
3. Play a music track
4. Access "Audio DSP settings" from OSD
5. Click on "Speaker / Output setup..."
6. Click on "Speaker distance..."
7. Click on "Cancel" button (or click Back remote button) and Kodi will crash
8. Crash log: http://sprunge.us/HAXa
