gmrender plays too fast #123

Closed bruxi closed 4 years ago

bruxi commented 7 years ago

Hi,

I'm having gmrender running on an Raspi 3 (built from jaeksch-fork) to play to a filesink from snapcast server. Everything works fine but the music plays a little too fast. My client from which I'm playing is BubbleUPNP, the music is served by BubbleUPNP server. When I play directly to the renderer installed on the Raspis in each room, the speed is ok.

Here's the log where you can see that there's a time drift:

gmrender is started like this:

/usr/local/bin/gmediarender -d -f Multiroom -u f7cbc54e571df7ceb530e2cd23952658 --gstout-initial-volume-db=-10 --logfile /var/log/gmediarender.log --gstout-audiopipe audioresample ! audioconvert ! audio/x-raw,rate=44100,channels=2,format=S16LE ! filesink location=/tmp/snapfifo Many thanks in advance!

It seems that snapcast is running with 48kHz the time shift is about the ratio 44,1/ 48. Please check the settings of snacpcast, or try 'rate=48000'

That did the trick, thanks a lot for the immediate reply
