Yup. Had same problem today. No audio when starting up. No warning signs. Just wouldn't give even a whisper, neither did Ms. On*Star.
When I went for next ride the audio worked normally again.
Read all posted advises and Tech Bulletins (by searching "audio").
Sent the dealer (Scotssdale Arizona, AZHummer) an e-mail, suggesting to send a new amplifier to Aruba for the GMC dealer here to replace. Will post outcome. JCJ
