My Amiga 1200 boots with the low-pass filter enabled

Hi.
 I'm not sure if this was happening from the beginning. (I think not?) I'm using a different motherboard and accelarator since then and i'd like to know if this is normal.
 My A1200 boots with the low-pass filter enabled (power LED at full luminosity) and sound ehm.. sounds really bad. I have found a way to correct this by adding a command that toggles the sound filter/LED in the startup-sequence. No big deal. I just want to know if this suppose to happen.
 Note that this isn't caused by some command, as i have tried to boot without startup-sequence from the early menu.

Yes.

Here's a low pass killer that can be run from startup-sequence: http://aminet.net/package/util/misc/NoLed

Ok then.
