Eeek. But enumerations from 0% to 40% sounds tedious. I'd just use a single value, it's a UI problem with the mixer and if the control isn't called "Volume" that shouldn cause the UI to not present it as a volume. He said hopefully. Or possibly a binary control I guess which would have the nice side effect of hiding from most non-specialist UIs. > And how would you suggest that I name the controls? > "Max Overclock DAC", "Max Overclock DSP" and "Max Overclock PLL"?

It's vanishingly unlikely that you'll cause physical damage with this sort of thing, you're much more likely to hit performance and filter problems than anything else. --4AmJdx/+JAF2YHMk Content-Type: application/pgp-signature; name="signature.asc" Content-Description: Digital signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iQEcBAEBCAAGBQJU6znDAAoJECTWi3JdVIfQl+gH/AnpHP5W6OZpwDEs3Y4GLMYp O5icFdKA0V9hKDbxbp2IvmQ01ipwFkaofGIoaCavexkBLvXMODibqPNHvfoB9eJU R81uaJ1KjJ8ro6hUQgukE1LPbY9uu6Vxls0f2amWaYAfVj97C6RfDsBYAOM1cfoe KTnkxZ/+R7G6z5HwJbXgABHEHh342SpDv0z0LJKbBXyV5Ljow/iec0t0RCWIg8MS 9nbGAdGxZ2NocPNKlpjtWeeEUEJ/io5iRVJjMD00YKKqu9l6b8VoAq+YRnmoufzz 4jiQQjpSYIhXipRPovmENQtK+blxLolChoG2R4gR9hd9S95/SStnsPyHpDENo8c= =lGW/ -----END PGP SIGNATURE----- --4AmJdx/+JAF2YHMk-- -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
