Question one newbie question about Alsa driver

Hello all,

I am running Rh9 and the sound card is working properly. However, it does not appear to support full duplex communication. I am thinking of installing the ALSA driver for it. But, I have some questoins here:

1. Is ALSA driver going to overwrite the driver I am using now? (I am a newbie to this)
2. The driver I am using now is directly built into the kernel, do I need to remove it? If so, how could I do?
3. If the new driver does not work, how could I restore the driver I am currently using?

Thank you very much!

I think if they're both loaded, they will clash (I don't think one will overwrite the other).

they're separate files if:
1. one driver is in the kernel (the driver is in the kernel file), and the other is a module.
2. each driver is in a different kernel.
3. both drivers are modules.

I don't think it's possible to compile a kernel with two drivers for the same subsystem, but I maybe wrong (it would be silly to do so).

you'd want to do #2 or #3 - I think it would be simpler to compile two kernels with different drivers, or make use of modules.
then you could switch between kernels (you can make them options at boot up), or you could load/unload the modules, which imo is easier.
