    You can run the lspci and lsmod commands to get some hardware and modules information.

    Code:
    lspci
    lsmod
    ...run man lspci and man lsmod for more info on each command.

    hmm, that seemed to work, however im not sure what to do with the output. The reason i ask is because im trying to use rdesktop. In the man pages for rdesktop it says to specify an audio device you need to include
    Code:
    '-r sound:[local[:driver[:device]]|off|remote]': enable sound redirection
    so i imagine that i would need something like rdesktop -f servername -r sound:local:esd:/dev/SOUNDDEVICE


    im just not sure what my sound device is.

    the output is as follows

    so my audio device would be

    how would i pass that into the rdesktop syntax of
    Code:
    rdesktop -f servername -r sound:local:esd:/dev/SOUNDDEVICE
    thanks

    I don't run rdesktop so I won't be much help there. Maybe somebody else can chimr in or these threads will help maybe?

    Sorry I can't be of more help to ya.

    FIXED Audio Over Rdesktop from Server 2008

    This one took a while, but after many hours of research a google junkie from work gave me a suggestion. "try adding -r disk:Z/mnt" to the command.


    Guess What...... It Worked.

    So my Rdesktop 1.6.0 command is now,

    Code:
     rdesktop -f server-IP -r sound:local -r disk:Z/mnt  -r disk:USB=/media

    Hopefully this helps someone having issues with Server 208 and Audio Redirection.

    First try:
    rdesktop -r sound:local
    rdesktop -r sound:local:esd
    rdesktop -r sound:local:oss
    rdesktop -r sound:local:alsa

    If you think you need device files try:
    ls /dev/dsp /dev/snd/control* /dev/snd/pcm*

    There may be others in /dev or /dev/snd

  11. #10
    Looked up this thread because I needed to know what the /dev sound device was. Have found out how to do it. So for the record:

    OSS device /dev/dsp and perhaps /dev/dsp1 etc..

    ALSA All the alsa sound devices are in the directory /dev/snd so 'ls /dev/snd' will list them.

    To find out which ones are being used, you might have got a message that it can't be used because it's being used by another program for example. 'lsof|grep snd'.
