i see someone reported a similar problem 2 weeks ago. UGH I should read better. So it sounds like ext usb sound card should do the trick at fixing it and you all can ignore my message. Sorry for the distraction.<br><br><div>

Hi all,<br>I'm hoping someone can suggest remedies for this problem I'm having in doing laptop recording.Not necessarily ardour related<br><br>Basically I got a really weird white noise-ish interference when I try to record through the line -in that seems to hover around 4db. Here's the strange part. If I unplug the ac adapter it goes away. So Basically I can record scratch tracks while running on battery (which lasts about an hour).
<br clear="all"><br>I've also noticed that if I route from the line out jack into my Roland 8 track I get an identical sounding hum/buzz that also goes away when I unplug the ac adapter. <br><br>I'm almost certain this problem is isolated to my residence because I do a radio show off my laptop through the line out with ac adapter plugged in and there is no hum what so ever in the studio.
<br><br>Someone wondered if maybe it has something to do with the internet access that the energy company offers maybe. So I'm wondering if there's any way to filter the current out maybe through an extra fancy power stripor something so that I don't get the hum when I record.
<br><br>FWIW. It's a HP Pavillion dv9000(snd-intel-hda) running the latest ubuntu and whatever ardour is in their repositories.<br><br>I'm getting an ext usb sound card delivered in a couple of days and I'm hoping that this helps but the problem is annoying.
<br><br>Any suggestions would be greatly appreciated.<br>-- <br><span class="sg">Thomas G. Willis
