Hello,
I am a Gentoo user who installed an Ubuntu system for a friend, and the process was pretty flawless except of one thing. My friend has two sound cards installed - Intel HDA on board and Creative Labs PCI external.
After the installer finished, there was no sound. The funny thing is - the right module for the Intel HDA card was loaded, and the jacks were plugged in - it should have worked. Well, it worked indeed, but, the sound was routed trough the Creative Sound Blaster one.
While it's a good thing to enable the better card by default, there was no seamless way to "force" ALSA to use the Intel HDA card. Therefore, here's my suggestion:
1) After first boot, if two soundcards are detected, ask the user for the preffered one.
2) In the Sound Configuration Menu add some seamless option to easily disable/enable selected sound device (by which I don't mean selecting Pulseaudio/Alsa/OSS, but the card itself).
No attachments.
