Not necessarily.  Based on the OP's original post, as well as his mails
to the LKML (Google the subject line to find them), he has a desktop
system with external powered speakers connected to a sound card, and also
a small PC speaker inside the system case.  He wants to hear the beeps
coming out of the small speaker, since the external speakers (and/or sound
card) are not always turned on.

For that, try turning off SND_HDA_INPUT_BEEP.

(Regarding the beep frequency issue, the patch in 2.6.31-rc1 works for
all HDA codecs *EXCEPT* sigmatel/idt.  For sigmatel/idt, please see the
patch in bug #0004556.)
