Hi all, I have an Asus A7T laptop which had a problem. Asus switched my motherboard to correct it but now i have no sound. I searched on the web and understood that the codec should be known by kernel in order to have sound. Here is some output : $lspci -v 00:10.1 Audio device: nVidia Corporation MCP51 High Definition Audio (rev a2) Subsystem: ASUSTeK Computer Inc. Unknown device 13c2 Flags: bus master, 66MHz, fast devsel, latency 0, IRQ 20 Memory at dceb8000 (32-bit, non-prefetchable) [size=16K] Capabilities: <access denied> $lspci -vn 00:10.1 0403: 10de:026c (rev a2) Subsystem: 1043:13c2 Flags: bus master, 66MHz, fast devsel, latency 0, IRQ 20 Memory at dceb8000 (32-bit, non-prefetchable) [size=16K] Capabilities: <access denied> So I have an unknown device and i wonder how can it be recognized ? I have a debian etch system with 2.6.20 and a debian lenny system with the latest 2.6.23.8 kernel from kernel.org but i have still the same problem. Can anyone help me ?
