#32 Not able to choose soundcard on linux

The sound cards available in linux are hard coded in
linuxmedia.cxx. The code tries these 2 devices, in order, then
gives up:

/dev/dsp
/dev/sound/dsp

I have onboard sound and an additional sblive. The sblive (with
the speakers connected!) is /dev/dsp1 (or /dev/sound/dsp1), so
I can't get bzflag to make noises very easily.

Shouldn't the sound device be a command line/configuration
option, or perhaps at least changeable by an environment
variable or something?

Cheers,
Cris

    While it would be nice to have an option to choose the sound
    card, it doesn't really make sense for /dev/dsp to not be
    your primary audio device. If /dev/dsp is a symbolic link,
    it should be easy to remove it and make a new link to
    /dev/sound/dsp1. Worst case you might have to remove the
    kernel module for your onboard sound, but if you don't use
    it that probably isn't a problem.

    But I do use the onboard sound... I use the onboard stuff for line and
    mic in from one audio source, and for mixing from some of the
    onboard hardware.

    I use the sblive for another line in and output to my digital speakers
    via the onboard surround sound etc.

    Yes, /dev/dsp is a link to /dev/sound/dsp, but if I move it, then my
    sound recording apps (which mostly only know /dev/dsp and
    /dev/dsp1) won't be able to record from the first sound device.

    Most apps have some way of changing audio devices or using a sound
    manager, so it didn't seem an unusual request. I could submit a patch
    for an env variable option (if it would be accepted), but it wouldn't be
    as 'neat' as having a proper switch or config setting.

    Cheers,
    Cris

    It is now possible, by a simple menu choice, to select the
    audio device and driver. The version is in CVS, and will be
    broadly available in the next version of bzflag.
