Airport Express (1st generation) won't stream music
Dear Apple community,
Since 5 or so years I have a first generation Airport Express (Model No. A1264), which recently has the following problem when used from both my iPad 2 Mini (running iOS 8.1) and my MacBook Air (running Yosemite 10.10):
Both devices do recognize the Airport Express and do also connect with it, but when streaming music (Spotify) through the Airport Express, the speakers don't give any sound (of course I checked and triple-checked that the problem is not with the speakers themselves ;-). Spotify plays, the iPad or MacBook are connected with the Airport Express but no music from the speakers. Immediately when I disconnect the device from the Airport Express the music can be heard through the device's own speakers, so the problem is not with Spotify as well.
I find this very odd, and have tried resetting all devices in question already (including the modem). The problem however is persistant, and to make things even morre complicated: sometimes both devices DO play music through Airport Express (I also have an iPhone 4 running iOS 7.1.2, which doesn not have the problem!). For instance, when I let my MacBook connect with the Airport Express through iTunes (which I don't use generally) and afterwards run Spotify, the music is audible. Through the iPad it does work sometimes as well, but recently more often not.
Again, the Airport Express is visible in both iPad and MacBook, and there is no error connecting (you can even hear a faint connecting sound from the jack cable when I put the speakers' volume on maximum, so something is clearly happening). Just no music can be heard while Spotify is streaming. Both devices connect with our AppleTV (2nd generation) as well; no problems there.
Any thoughts? Is this perhaps because my Airport Express is too old and is not compatible with newer versions of OS and/or iOS? I am very grateful for possible solutions from experts, since I myself am quite the humble Apple amateur :-)
Last note: the Airport Express is connected wiressly with our ADSL modem. Average ADSL speed is 5-7 MB (download), so not very fast. However, Spotify runs quite smoothly on both MacBook, iPhone and iPad. Airport Express connects with our WiFi signal, does not expand nor creates it. Airport Express only used for streaming audio.
