This is an Update to the original low audio output post:
After contacting Dell Small Business Tech Support. Dell shipped me a replacement U3014 monitor via overnight FedEx. After I connected to my system and powered it up I was pleasantly surprised in that digital audio sent via the HDMI and DP ports was NORMAL. Further the U3014 display screen had no visible corner backlight bleed-through, as is "normal" for this display. But the strong IPS "glow" limits how close you work to the monitor screen.
However, after about 30 minutes the audio level being fed from the U3014 Audio Out jack to the Dell AX510 dropped way down. A different sound bar did NOT help. When I connected the Audio Out jacks from my U2713H and the U3014 monitors to Sony Sound Forge Pro 10's six-channel audio level meters and saw the same 13 dB drop in both channels that the first U3014 suffered from.
Both the U2713H (audio channels 1 & 2) and the U3014 (channels 3 & 4) were fed the same DirecTV HDMI output. The peak recorded levels are at the right end of the green level bar displays. These show the difference between the audio out jacks on the two monitors. The U3014 output is 13 db below the U2713H output. When first turned on the U3014 was identical to the U2713H! After 30 minutes the U3014 audio output level dropped.
My guess is that some thing in the digital audio decoder failed. And, since the two U3014 monitors are close in serial numbers, this failure will probably happen is all U3014's from the same manufacturing lot.
Since most U3014 users will not to monitor the embedded digital audio on the HDMI or DP inputs, there will not be too many reports of this problem. Those who plan to use the U3014's to monitor both audio and video on the HDMI or DP input jacks need to check for this problem.
