V1.3.9 playback hangs on quiet passages
Posted: Wed Nov 11, 2009 4:36 pm
I'm using Audacity v1.3.9 on Ubuntu v9.10 (Karmic). The hardware setup is a Tyan Thunder motherboard with twin AMD Opteron processors, 8GB RAM, about 1TB of SATA HDD and nvidia on-board sound.
I have a regular weekly task: to take the recordings of services at our church (recorded on audio CD), rip them to my PC, extract the sermon, save it as an MP3 file and upload it to the church web site. Back in the days when I was using Ubuntu 8.04 (which offered Audacity v1.2.x I think) this worked fine: I used Sound Jiucer to rip the CD tracks to flac files, imported the appropriate flac file into Audacity, trimmed off the psrts I didn't want and exported the sermon as an MP3 file. When I upgraded to Ubuntu 9.04, Audacity was upgraded to v1.3.7, and I first hit the problem which is the subject of this post. As a work-around I was able to build Audacity v1.2.6 from source, and continued to use that. I recently updated to Ubuntu v9.10, and found that it had disabled my Audacity v1.2.6 executable
I've been scratching around with no success trying to rebuild Audacity v1.2.6 from source, with distinct lack of success (I'll post about that separately...), so I thought I'd post to see if anyone can suggest a fix for the problem with Audacity v1.3.9.
The problem is that when I try to play back the flac file I've just imported, Audacity starts off OK, but stops playback when it hits a quiet passage, If I move the cursor on a bit to where the sound volume is higher, I can restart playback, but I need to be able to locate the quiet passage just before the speaker starts the sermon, and when playback stalls this is made difficult. Can anyone suggest how to track down the root cause and fix it, please? If detailed diagnostics would be needed, let me know and I'll dig out what I can.
Thanks in advance for any help
