Not 100% sure if this is correct on my part ... but if some other
process is using the audio driver, then Audacity can't. So, stop the
other process using the driver :)
In my Gusty I run KDE and have set the Auto-Suspend after idle in System
Settings -> Sound. I run this with a 30 second timeout. So, if I have a
mp3 player running I just stop it; wait 30 seconds, then run audacity
and it all works.
It appears your friend has the correct audio drivers.
hope this helps.

hi
I and a friend are both having problems using Audacity to edit music
files. In my case, I am trying to edit an .ogg vorbis file, and in his
case, he is trying to edit a file that he recorded with Audacity. He is
a 69 year-old man, and I am trying to assist him over the phone, so it
is kind of hard to get complete details from him, but, fortunately, I am
having the same problem on my Gutsy install with Audacity 1.3.3-beta.
Here is the exact error message that we are getting:
Error while opening sound device. Please check the output device
settings and the project sample rate.
I have googled and found that there are a lot of problems with Gutsy
getting this error message. The suggested solutions fall into two
camps, neither of which has worked for me. The first camp is grepping
for the jackd process and killing it in the shell; the second involves
making sure that you have sound privileges (we do) and that you are
using the correct sound device (not sure how to tell about that). The
helpful links on these topics are below:

Grepping, I get no responses to jackd at all:
cje@rb:~$ ps -e|grep jackd
cje@rb:~$ ps -A | grep jackd
cje@rb:~$ ps -A | grep jack*
cje@rb:~$ ps -A | grep jack
cje@rb:~$ ps -e > jackd_test.txt
cje@rb:~$
As you can see, I directed the grep output to a txt file, and I looked
at the txt file, and sure enough, no jackd. So that solution won't seem
to work.
With regard to the potential solution of choosing the "correct" sound
device, as suggested by the second link above, I went to
Edit > preferences > Audio I/O
and found that these are my choices: not sure which are right, and I'm
not sure I want to go messing around with settings until I know what is up:
ALSA: HDA ATI SB: ALC883 Digital (hw:0,1)
ALSA: default
ALSA: iec958
ALSA: spdif
ALSA: dmix
Thanks in advance for any help!
