Frequently Asked Questions:

How do I get my Videos to play sound?

First, make sure that your Monitor has speakers, or attach speakers to the Monitor or your DAKboard CPU. DAKboard Wall Displays have speakers built in. Next, make sure your Video has an audio track. If you are using YouTube, check your block to see if the volume is set (see our article How to Add a Video Block to your DAKboard Screen for details). Finally, double-check that the volume is set on your DAKOS Settings page (see our article DAKOS Display Settings for details).

Can DAKOS be installed on any PC?

No. DAKOS only works with a select few Raspberry Pi microcomputers or the Orange Pi 3 LTS. Though it is Linux-based, it is built on versions of Linux that only run on these devices. See our articles Raspberry Pi - Download and Install the DAKOS and Legacy Orange Pi - Download and Install DAKOS for the full list of supported CPUs.
