Machine: Lenovo Thinkpad T61 Firmware: 7LETA7WW (2.07) EC: 7KHT24WW-1.08 I just tried your test and none show anything. I was playing music and when I pressed the mute button it muted. This is with my using NO kernel parameters. It did not show this in the amixer output. I think the firmeware may be going right to the speakers and muting them as opposed to the HDA mixer. I have my logs attached. But all are the same.
