[Bug 498139] Re: sound stops working after kernel upgrade intel, ICH7 HDA

Mon May 3 14:54:21 UTC 2010

Hi Jeremy,

As I am having the issue with my fathers laptop I can not regularly test it.
Though, it is becoming more and more obvious that it may also be a hardware
issue, since I have observed behaviour where from one booting to the next
sound stoped or started working, nothing else changed. Moreover, the
bugreports I can collect from my father are not very reliable... Last status
is at least "it works". I am going to test the issue with a live ISO when I
can grab the laptop next time.

By the way, as last status is "it works", I would not object to close the
bug, resolution "inconclusive".

Kindest Regards,
Simon
