<html> <head> <style></style> </head> <body class='hmmessage'> Hi Guys<br><br>I bought an Acer Aspire One 521 netbook last week and, of course, immediately got rid of Windows 7 and put Xubuntu 10.10 on instead. Unfortunately I cannot get the headphone socket to work, no matter what I try. Since the netbook's main role will be as a media player, this is something of a problem. The socket worked fine under Windows 7, so I'm satisfied it's not a hardware failure.<br><br>In my investigations I discovered that the BIOS is v1.01. The latest version on the Acer website is 1.10, so I'm sorely tempted to upgrade it, in the hope that this might deliver a solution. Trouble is, I've no idea how to go about it. Can anybody describe the process and, just as importantly, advise whether BIOS is a possible cause of the problem in the first place?<br><br>Thanks very much.<br><br>Nige<br> </body> </html>
