Hello
I would like to disable the internal mic at boot is this possible?
I have tahr64 605 frugal installed on a dell vostro 1320, 2.2ghz,2gb ram. The main reason is if I record what the soundcard is playing using andacity I also get what the mic is picking up and its noisey. I have set mic and mic boost to zero in alsamixer.
Has anyone any ideas.
Thanks

I solve this by plugging a 1/8th plug with the cord cut off into the mic input on the PC.

Works like a charm ..

That has historically worked but isn't guaranteed to work into the future. The only sure way to ensure no mike is to rip it out....but I suppose that I'm getting off topic.

I cant try the plug idea at the moment as two seperate puppys will not record anything, I even tried my wifes pc, it wont as well.
I will try it as soon as I get something to work. In the meantime thanks.
