Hi Sunny,

From the specs:
HP BIOS with enhanced ACPI, DMI, Green, and PnP Features Plus

Theoretically, the HP BIOS could be 'optimized' to support some factory
installed (M$?) software. You could test this by flashing the BIOS with an
'off-the-shelf' image from ASUS. I'm not convinced this is your problem,

First, I wouldn't expect an IRQ problem to exhibit a symptom like this. The
device should either be recognized, initialized and work... or not, if the
problem is really IRQ. If you drop to 8KHz sampling rate x 8 bit samples,
does the recording time increase before the microphone "breaks?" This could
be a broken buffering scheme, i.e. software bug (broken module?)

What happens if you do a 'line' recording?... if you record from streaming
radio, does it also go silent after a second or two?

Have you tried all of the relevant boot kernel parameters?
