A1 supports 16bit/176kHz, but does not support 24bit/176kHz
A1 does not support digital signal from iDevices
A1 does not support HTC Android 4.3
A1 does not support SPDIF out from DSD playback
At low A1 battery charge the Android signal may disconnect
Adjust the Foobar output function Buffer length to 1030ms to ensure smooth playback. 
When the battery charge of the Android device runs low (10~20%), music playback may stop. 
Reason: Android devices are programed to cut digital signal output at low battery charge. 

When playback is initiated on the connected Android device or during playback, sound comes from the Android device and not the A1 
Reason: Battery charge on the A1 is too low to receive digital signal input from Android device.
