I have finally build myself a working multiseatet system. The only thing i need to setup correctly is sound. I have a P965 chipsset with Intel HD audio. I've added both users to the audio group and audio works from both seats. But what i really want is to use one of the six jack connectors on the back for one seat and another for the second seat. I found this http://wiki.c3sl.ufpr.br/multiseat/index.php/How_to_make_the_sound_work , but according to /proc/asound/cards it only sees my sound card as one device. Do i really have to sacrifice a PCI slot or is there some way around that? -- Lasse Jensen <fa...@gm...> |

Then certainly the easiest thing is to use two sound cards. It would probably be possible by combining the two sounds into one 4 channel sound to get different sounds to the two outputs, but it would be a real kludge, and liable to breaking down, IMHO. |

Something based on this may work for you - I know it works for a single user. I don't know whether there are reasons that it won't work for multiple users. The sharing of the underlying hardware device will be based on trust i.e. one of the users could occupy the six channel device and prevent the other user from accessing it. http://alsa.opensrc.org/index.php/.asoundrc#Splitting_front_and_rear_outputs |
