view story

http://ubuntuforums.org – Weird Sound Card Problem I have a HP IQ504 computer with a AD1984B sound card, the OS recognizes the soundcard yet it can't play audio unless it has headphones plugged-in. Also it only plays with the Analog Stereo Duplex profile. I've looked everywhere to make the internal speakers work, yet am still here Tell what do you need to know about the config files, ect. Most definatly I am a noob when it comes to UNIX based systems, so please tell me what should i do, please,... i am done with win7 (Hardware)
