Assus G78 i7, 8 or 16gb, Audacity 2.1.1, KDE 5, 1TB 2.5" disk
I seldom get more than 8-9 minutes worth of recording without a lockup or crash, sometimes to the sound of buzzing sounds. I’ve seen some reports related to USB so I make sure that no user app is running and that no peripheral is plugged-in while recording. What I did notice however is that each time I restart following such an upset I get invited to resume the former operation or dump everything and start all over. The disk is 1TB 2.5" so I wonder if the problem would rise from some continuous backing up or something similar i.e. the disk not being able to keep up? These are practice sessions so I need no backup whatsoever.
The reason I go past the typical 3-4 minute song length is that I start practice and record every attempt, I could do this for an hour before I either get fed up or hit upon the proverbial ‘that’s a wrap’. “Track-delete and restart” for each pass doesn’t turn me on that much and I could on average record 20 minutes as a minimum.
What audio device are you using? Is it the built-in sound card in a laptop PC?
Are there any other audio devices connected to the computer?
What settings are you using in the device toolbar?
Try setting both the recording and playback devices in the device toolbar to the “hw 0:0” option.
This method can usually only be used when Audacity is the only audio app running, but it bypasses PulseAudio and is generally more stable both for playback and recording.
