I ordered a normal FireTV stick some weeks ago, then returned it the other day for exchange to a 4k model. And with the new 4k model I get no audio output anymore. Audio worked fine with the normal FireTV stick.
I have the following audio/video line:
FireTV stick -> hdmi cable -> hdmi/spdif splitter
-hdmi> PC Monitor
-spdif> Edifier R1280DB stereo speakers
This worked totally fine with the normal FireTV stick, but whatever I try, I cant get any audio out with the 4k model.
Audio is set to "stereo" under settings, but that does nothing. Tried latest firmware, rebooted several times. No Audio.
If it is set to Stereo, anything Dolby related (dolgy digital ect) should be deactivated and it should just use PCM Stereo over HDMI/Spdif. It worked fine with the normal FireTV stick but not anymore with the 4k stick.
