I have successful video display by chaining 2 Dell U2414H monitors with a sound bar. I do not have any sound. In the volume mixer I can see both Dell U2414H monitors and one will show that sound is playing, but nothing is coming out of the sound bar. The monitor/sound bar configuration is connected properly and works when tested with another computer using HDMI cable. I am not sure if this is an SP2 problem, displayport cable problem, or issue with the displayport sound via the monitor. It does show that monitors using "Intel Display Audio". The picture shows the setup and that the sound is being played but I am not able to get anything out of the speaker. I have tried swapping the default monitor etc. Nothing seems to work.
