Sound Through the PC-Speaker
PC-Speaker is a neat bit of software that makes good use of the basic speaker. Be warned—you will get plenty of interference if your computer is digitally noisy. It is unlikely to become part of the standard kernel; the author, Michael Beck (firstname.lastname@example.org), tells me that one of the reasons is that the driver interferes with the Linux clock. I haven't noticed this myself, but my clock is re-synched with my ISP's clock four times a day. The distribution comes with a file that describes how to build your own sound output devices. For example, using these instructions you can connect your PC to your amplifier.
