Re: kern/51784: "Synthesized" speaker hums

[Nathanial Sloss <nat%netbsd.org@localhost>]

Hi,

I've since found there is quality loss converting from ulaw to signed linear.

I now have a 16 bit 1 channel signed linear bell.

To use apply this patch:
ftp.netbsd.org/pub/NetBSD/misc/nat/hiresbell-linear.diff
and add the following to your kernel config:
options HIRES_BELL

Please let me know if this resolves the "hum" this time?

Best regards,

Nat
