Re: pc speaker module

[Anticipating a Reply <ruxyz@yahoo.com>]

Hi Fabbri,

  I'am a newcomer too .

  I found your topic interesting , 
but the link seems to be removed .

   I think writing a driver for 
controlling the PC internal speaker 
would be a very interesting learning 
experience .

  Can you give me more information 
on this topic and the driver source too .

  Thank You .

With Best Regards
