So, today I started my home music production career and I bought myself an M-Audio Avid recording studio, very simple to plug and set-up got myself into playing 5 minutes after. The only problem that I have is that when I use guitar rig 5 there's an intermittent sound when it starts usually at 512 samples which makes me put it up to 2048 samples and increase the delay up to 100 ms. The lower I go on the samples the more that intermittent sound appears, when I'm on 2048 it still appears every 5 to 10 seconds and the asio4all green icon becomes red with an exclamation mark, another thing that I'm curious about is that my sample rate can only be 44100 or 48000. I have tried the antivirus deactivation, the internet connections and closing all the programs but it wont make a difference. my specs are Processor: AMD A6-3420M APU with Radeon(tm) HD Graphics 1.50GHz Installed Memory (RAM): 4.00 GB (3.48 GB usable) And I'm not entirely sure but I think my internal soundcard is IDT High Definition Audio CODEC? maybe? And I'm using a M-Audio Avid Recording studio USB interface. Thanks for your help, Horacio!
