To summarize, aliasing is the result of the _sampled_ nature of a

That is true for your particular example, but aliasing artifacts

The levels in alsamixer are all set to 100 -- can this cause clipping,
and if so, would this account for the aliasing? I understand that

Weird. Anyway, download the latest alsa, compile it and install it.
Hello,
I have an IBM T41 laptop with an Intel8x0 built-in sound card that
generally works fine under alsa. I have been trying very hard to get it
to play friendly with mythTV and my Plextor PX-TV402U-NA. The developer

That is not how ALSA works. You use device names like hw:0 or hw:1,
not /dev nodes.
