Non exclusive sound device access!!

Hi,
I was wondering if any of you guys know of way to make applications that use sound device on linux to access it in a "non-exclusive manner", the aim is to be able to use more than one application that requires the sound device.
Thanks

NAME
snd_gusc -- Gravis UltraSound ISA bridge device driver SYNOPSIS
To compile this driver into the kernel, place the following lines in your kernel configuration file: device sound device snd_gusc Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5): snd_gusc_load="YES" Non-PnP cards require the following lines in device.hints(5): hint.gusc.0.at="isa" hint.gusc.0.port="0x220" hint.gusc.0.irq="5" hint.gusc.0.drq="1" hint.gusc.0.flags="0x13" DESCRIPTION
The snd_gusc bridge driver allows the generic audio driver sound(4) to attach to Gravis UltraSound sound cards. The value of flags specifies the secondary DMA channel. If the secondary DMA channel is C, set the flags to (C | 0x10). For a sound card without the secondary DMA channel, the flags should be set to zero. HARDWARE
The snd_gusc driver supports the following sound cards: o Gravis UltraSound MAX o Gravis UltraSound PnP DIAGNOSTICS
