Musannaf Ibn Abi Shayba 3:1299

Abu Khalid narrated to us, from Yahya ibn Sa'id, from Abu Bakr ibn 'Amr, who said: 'Amrah stayed the night with us. I stood up to pray, and I lowered my voice. She said: "Will you not recite aloud? For nothing used to wake us up except the voice of Mu'adh the reciter and Aflah, the freed slave of Abu Ayyub."
