Hi,

 

During my journey to get my tv to actually play my media, I discovered some rather unpleasant device behaviour.

This issue reported here obstructs debugging of other issues by flooding the emby server log file with error messages.

 

My TV: A Sony KDL-55W807A https://www.google.com/search?q=KDL-55W807A

I installed all software patches available.

 

TL/DR: Volume control throws errors when external speakers are used.

 

Long story:

 

When I playback video files, emby server seems to want to request/query/control the current tv volume (I guess to remote control the playback using the web interface).

 

Notes about the log:

  • 192.168.1.85 is the IP address of my tv
  • /opt/ffmpegnv/bin/ffmpeg is a custom, nvenc-enabled build of ffmpeg
  • I renamed my tv to "Fernseher". I didn’t like the vendor-assigned name …

When the internal speakers of my tv are activated, this works as intended. Excerpt from the log file:

2017-03-10 21:00:21.1699 Info HttpClient: HttpClientManager POST: http://192.168.1.85:52323/upnp/control/RenderingControl
2017-03-10 21:00:21.1823 Info HttpClient: HttpClientManager POST: http://192.168.1.85:52323/upnp/control/RenderingControl
2017-03-10 21:00:21.2216 Info HttpClient: HttpClientManager POST: http://192.168.1.85:52323/upnp/control/RenderingControl
2017-03-10 21:00:21.2345 Info HttpClient: HttpClientManager POST: http://192.168.1.85:52323/upnp/control/RenderingControl
2017-03-10 21:00:26.2098 Info HttpClient: HttpClientManager POST: http://192.168.1.85:52323/upnp/control/RenderingControl
2017-03-10 21:00:26.2609 Info HttpClient: HttpClientManager POST: http://192.168.1.85:52323/upnp/control/RenderingControl
2017-03-10 21:00:27.1969 Info HttpClient: HttpClientManager POST: http://192.168.1.85:52323/upnp/control/RenderingControl

But I’d like to use my 5.1 sound system connected via an optical SP/DIF cable. So when I configure the tv to output the sound to SP/DIF and pass-through all incoming (compatible) audio streams, the tv disables the internal volume control completely, because it cannot work with bitstreamed, compressed audio.

This causes the tv to respond to each request to query/modify the volume with a HTTP error 500. Another (small) excerpt from a log file, after enabling audio passthrough:

2017-03-10 22:16:16.9905 Info HttpClient: HttpClientManager POST: http://192.168.1.85:52323/upnp/control/RenderingControl
2017-03-10 22:16:17.0418 Error HttpClient: Error getting response from http://192.168.1.85:52323/upnp/control/RenderingControl

Those error messages output vast amounts of text, because emby-server indefinitely retries the failing HTTP queries for as long as video (and probably audio streams too) is played back.

 

I’d like to get rid of those errors, and no, disabling my 5.1 sound system and using the tv speakers is not an option ;).

These errors seem to not affect the server stability.

Possible solutions:

  • Allow disabling the volume remote control of UPnP devices (maybe on a per profile base)
  • Disabling the volume remote control automatically when receiving a HTTP error code from the device.

I did some further research (which i should have done before creating the thread…).

Result: This is related to the "DLNA Play To" feature. When using this feature, the web frontend allows remote-controlling the playback. This remote control has an audio volume slider that is supposed to control the renderer volume and display the current volume.

 

When using an external sound system this volume control ceases to work, because the tv responds to all audio related request with HTTP error 500 (*).

 

Not being able to control the volume in this case is not a bug in emby-server, but it could handle it a bit better.

 

Feature suggestion:

When volume control fails, disable/hide the volume slider and (maybe) display something like »This renderer does not support volume changes using this web interface.«

 

(*): This specific Sony device does it that way, others may silently fail or fail with other status codes.

 

Edit:

But after thinking about it a bit more, the current implementation may be just fine. I may have been to obsessive with "no errors in log files!" when posting.
