Wiim Ultra transcoding issue

[yaleforks]

Interesting. How did you discover that? Please go in detail some more.

This is a known issue with PlexAmp and the more recent Chromecast hardware/firmware, we think.

I got an Ultra to replace one of my Pros. It's been great and I have phono functionality now. I am, however, having issues when streaming Plex through Chromecast. Plex is transcoding my files playing within the home network on the Ultra. It isn't doing this with my Pro that I have upstairs. It's doing this from either Android or iOS. If I use the Plex integration in the Wiim app I can't tell if it's direct playing as it doesn't show up on my Plex server as playing from the server. Any help or guidance to change the Chromecast settings would be great. Right now it's taking FLAC files and...

Aha, right. You're playing a MP3 file from your library which is transcoded to Opus. A WiiM is certainly able to play MP3 files directly but maybe your files are in a not compatible form, non standard bitrate or VBR or something. What is shown in the Plexamp player when you play the exact same file to a Chromecast Audio?

They are .flac files. It's only happening on the Wiim I can cast to over 10 other devices and it plays with no transcoding. Playing to another device just results in a direct play

Thanks!! Yep seems to be the same issue. I guess I'll use one of my NUCs to run plexamp headless and run that to the Wiim

Remember I'm trying to help you. You did not elaborate, just posted a screenshot I interpreted and I was wondering how Plexamp looks when playing to one of your over 10 other devices...It sounds like you are annoyed by me or maybe I sense that wrong but I wish you good luck.

Yeah I think you are reading too much into it . But looks like this is known bug. Here is how it looks casting to a different device.
