Hello,
I have a solution: the app BubbleUPNP for Chromecast. It transcodes audio on the go. However, the perfect solution would be to install BubbleUPNP Server on the NAS to let it do the transcode and not the phone, however it is not possible since we can’t install “regular” packages on v4 firmware.
You can support my request here: http://community.wd.com/t5/WD-My-Cloud/Repository-with-software-worked-on-v4-firmware/td-p/829720/highlight/false/page/12
