one newbie question about Alsa driver
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!
