I have tried searching google for my problem, but I can't seem to find the solution to my problem, even though there obviously are other people having the same problem (mostly in different tastes of Ubuntu). None of the solutions I saw on other sites is working for my system. The weirdest thing about this problem is this: Yesterday I installed Linux Mint 5 (Elyssa), and did no configuration of the audio, except choosing the audio-mixer to use under wine, to get music playing from Spotify. This night I wanted to try to upgrade from Elyssa to Felicia, but it went wrong, and I installed Elyssa from a CD again. This time, the problem described in the text under and in the topic-title came along, even though I haven't configured any audio-options (yet).
My problem is that when I am playing music (or any other sound), the sound is coming from both the laptop speakers and the external speakers or headphones plugged into the mini-jack.
I'm currently running Linux Mint 5 (Elyssa) on a HP Compaq nx6325. HP's website is saying this about the audio for my laptop:
PremierSound audio/speaker subsystem
ADI1981HD High Definition CODEC
Integrated 16-bit Sound Blaster Pro compatible audio
Integrated stereo speakers
External volume up, volume down, and mute buttons
Stereo headphone/line out
Stereo microphone in
I'm sorry if I explain in a hard and non-understandable way, and you have to tell me if I really do, because then I will try again. Thank you.
