I have installed the Ubuntu 10.04 on a HP Pavilion dv3-2150ep laptop and I can't get sound on my headphones when I plug them. Besides the laptop speakers don't shutdown either - like it happened with the same OS on my Toshiba Tecra M4.
"aplay -l" lists my card properly and nothing is muted on "alsamixer". It states that my card is a HDA Intel with chipset Nvidia MCP78 HDMI.
Any thoughs on how can I crack this?
Thanks in advance.
