W/AudioGroup﹕ device loop timeout

问题

i'm trying to do a SIP call in my android. Sound works great on the first call, but when this call is ended and i start a second call, sound is interrupted and i get following warning (multiple lines per second):

W/AudioGroup﹕ device loop timeout`

I start the call with:

mSipManager.makeAudioCall(
    getAccount().getLocalSipProfile(),
    getAccount().getPeerSipProfile(),
    new SipCallListener(),
    0
);

Contents of call listener:

@Override
public void onCallEstablished(SipAudioCall call) {
    call.startAudio();
}

@Override
public void onCallEnded(SipAudioCall call) {
    call.close();
}

// ...

Any idea how to solve that problem?

Thanks in advance

Matthias

// EDIT: Currently i can reproduce this behaviour only on a Nexus 5 with Dalvik runtime. Changing the Runtime to ART "solves" the problem for this device, but it's not an acceptable solution.
