Hi. How do you use alsamixer as a blind user then? I'm using a braille display. I used it, and I had to guess what I was doing all the time. I've read that some cards doesn'tt support the hardware solution. How much delay do you thing I will get with the software way? So much as I get in windows? There I got such a delay/echo that I Went cracy. /Kristoffer 2015-07-23 3:19 GMT+02:00, Joel Roth <joelz@xxxxxxxxx>: > Kristoffer Gustafsson wrote: >> Hi. >> I would like to do some Linux podcasts. >> to do that I want to record the things from my soundcard. >> And I also want to get the sound from my microphone into my headset so >> I can hear what I'm doing, and get that recorded at the same time. >> Have you done such a thing Before? >> /Kristoffer > > Hi Kristoffer, > > Even the cheapest built-in soundcards can be used for > recording and playback under Linux. > > Live monitoring depends in some part on the abilities of > your soundcard. > > Hardware monitoring, if your soundcard supports it, > will let you hear what your microphone picks up without > delay.
