Re: [BUG] buggy ali5451 driver

[Olivier Ricordeau <olivier.ricordeau@wanadoo.fr>]

Hi folks!
I am Olivier, the owner of this laptop.
If there's is anything I can do to get my sound card supported by alsa, 
I'd be glad to help! So if you need me form some testing, just mail me! 
(I've also subscribed the list)

I'm in deep shit if I don't manage to get the sound working on my laptop...
