Hi, Using my Onkyo AV receiver as airplay receiver, When I play on a LMS group player, witch include the Airplay bridge player to my receiver, I have noticed that metadata displayed by my receiver are those of the previously played song (info, coverart and current/total timecode)....

ospring commented 5 years ago

More precisely, it occures at the end of the first song, displayed metadata is not refreshed with the next song and it stays to the current song (timecode go back to zero). aftewards, after the end of each song, it refresh with metadata of the previous one....

It seems to be related to the audio delay settings in corresponding LMS player settings witch is 1190 ms for my AV receiver

philippe44 commented 5 years ago

The metadata are gathered 1 second after the track starts, hence the problem you see. My do you need to set such audio delay?

ospring commented 5 years ago

It is empirical : I noticed a delay between 2 grouped player : my AV receiver (AirPlay) and my computer (airplay via « air server » app). The player (not plug-in, in the sync submenu of lms player settings) audio delay settings seems to help correct the delay and the value of 1190 ms was needed to sync the audio (with the help of my hears ;) ) Maybe another setting can help me but I did not find it for the moment.

Note that when using iTunes client on PC and activate these two AirPlay target , the delay also exist and seems to be the same (but I did not mesure it and I prefer use the LMS system witch offer synchronized play)

Oh I highly recommend you use squeezelite on your pc as well. Delay is stable and minimal and it’s a real SB client

ospring commented 5 years ago

It is not the pc airplay client who has the delay problem, it is my amplifier Onkyo TX-NR656 (AV receiver) witch is late by 1190 ms....

hmmm ... that's very strange. Have you tried to sync it with another real SB device? I've never seen an AV receiver with such latency. I think that the PC forcing you to do that

Hi,

I have tested with squeezelite for Windows in sync with the bridge airplay player of my AV receiver and I have the same delay (with 0 as delay in the settings of LMS player) Note that when playing with iTunes client to both airplay on Windows (Windows air server) and airplay of my receiver I Have this 1sec delay too...
