Except for CD audio, sound is working fine on my new HP G61 laptop
with kernel I can play CD audio fine in Windows.

IIRC, on my (very) old Dell laptop, alsamixer showed a CD audio
device, but that's not the case on the G61. I have asla built as

Extract from dmesg:
HDA Intel 0000:00:1b.0: PCI INT A -> GSI 22 (level, low) -> IRQ 22
HDA Intel 0000:00:1b.0: setting latency timer to 64

Let me know if there is any other information I can provide.
