Hello,
I have been troubleshooting a Google Cast playback problem with Symfonium and Google Nest Mini speakers. I believe I have isolated the issue quite well.
Symfonium version: 15.1.0 (127812) Beta
Devices: Google Nest Mini, both individually and in speaker groups
Audio: FLAC (16-bit and some 24-bit) and MP3
Casting: Google Cast
Problem
When casting a remotely stored track from Symfonium to a Nest Mini, playback starts but the track is skipped after a variable amount of time, usually between 4 and 25 seconds.
In Symfonium 15.0.1 (127798), the progress display showed something like:
00:03 / --:–
The track was then skipped.
In 15.1.0 (127812), the duration is now displayed correctly, for example:
00:00 / 03:25
However, the track is still skipped after 4–25 seconds.
The player then closes, although the Symfonium application itself remains open.
Cloud providers tested
I tested the same behavior with all three providers:
Google Drive — fails with Nest Mini
OneDrive — fails with Nest Mini
Yandex Disk via WebDAV — fails with Nest Mini
Therefore, the problem does not appear to be specific to one cloud provider.
Other devices
The same remote files work correctly when casting from Symfonium to a WiiM Pro:
Google Drive → Symfonium → WiiM Pro via Chromecast: works
OneDrive → Symfonium → WiiM Pro via Chromecast: works
Yandex/WebDAV → Symfonium → WiiM Pro via Chromecast: works
I also tested UPnP to the WiiM Pro:
Google Drive → Symfonium → WiiM Pro via UPnP: works
Yandex/WebDAV → Symfonium → WiiM Pro via UPnP: works
OneDrive → Symfonium → WiiM Pro via UPnP: fails with “Too many playback errors”
Local files
The same type of files downloaded locally to the phone play correctly on the Nest Mini through Symfonium.
BubbleUPnP comparison
This is perhaps the most interesting part.
Using BubbleUPnP with the same cloud providers and the same Nest Mini speakers, playback works correctly.
BubbleUPnP also works when combining tracks from different sources, including Qobuz.
Therefore, my network, Nest Mini speakers, Chromecast infrastructure and audio files appear to be working correctly.
Summary
The problem appears to be specific to:
Symfonium → Google Cast → Nest Mini
when the source is a remote/cloud resource.
It occurs with FLAC and MP3, and with Google Drive, OneDrive and Yandex/WebDAV.
The same cloud files work correctly with Symfonium on other Chromecast devices (WiiM Pro), and the same files work correctly on Nest Mini when using BubbleUPnP.
I originally noticed this after a Symfonium update. Yandex/WebDAV had previously worked correctly with Symfonium on all of my devices.
I would be happy to provide logs or perform additional tests if needed.
Thank you.
