I send this as a bug report:
Dear Sirs,
I want to report a bug:
subject: airplay on apple tv 3 is not working, when apple tv is in sleep
Probably since firmware version 7 of apple tv.
Situation:
Apple TV 3 reset to „restore“
Firmware 7.03
Bluetooth off
„Sleep after“ 15 minutes
audio connected via digital audio out
hdmi connected to panasonic tv
Connected via network cable to apple airport extreme Modell A1408 Firmware 7.6.4
apple airport extreme connected via network cable to modem/WAN
iphone 6 Firmware 8.1.3 connected to airport extreme via wifi
scenario;
apple tv 3 is in sleep after 15 minutes
take iphone
start iphone app music or “fstream" to listen to internet radio
select and activate an internet radio stream in "fstream"
activate control center
tap on airplay
select "apple tv", the blue marker indicates "apple tv" selected
no sound from apple tv
after 3 seconds, the blue marker goes back on top of the list to "iPhone"
select "apple tv" again, the blue marker indicates "apple tv" selected
no sound from apple tv
after 3 seconds, the blue marker goes back on top of the list to "iPhone"
and so on…
The control center on iphone shows the "apple tv" in the device list and then that entry disappears for some seconds and then is shown again.
sometimes there is not even an airplay button in the control center
A Panasonic TV is connected with the apple tv 3 via hdmi.
I turn on the tv and select apple tv as input. The screen is black.
I take the apple tv remote and press "menu"
The apple tv home screen appears.
take iphone
start iphone app music or “fstream"
select and activate an internet radio stream in "fstream"
activate control center
tap on airplay
select "apple tv", the blue marker indicates "apple tv" selected
Now there is sound from apple tv
Same behavior with iphone music app.
Same behavior with ipad air 2
When I get a connection then it is playing continuously without interrupts.
When I set apple tv 3 setting „sleep after“ to "never", the apple tv was working well for 3 weeks!
With Bang&Olufsen Beolit-12 connected to airport extreme via wifi there has never any problem with airplay.
Since apple tv does not play with airplay from sleep mode, I activate the apple tv 3 with the remote. It is wotking then. After about a week like that, the apple tv 3 is not even shown in the list of aiplay devices in the phone, when apple tv 3 is in sleep mode.
