xpdf blocks sounds
 
Hello,

I have been having this problem lately: I cannot get any sound to play
whenever I have some pdfs open.
Here's the output of 'lsof |grep snd'

nishita@ff9:~$ lsof |grep snd
lsof: WARNING: can't stat() ext3 file system /dev/.static/dev Output
information may be incomplete.
mixer_app 2960 nishita 38u CHR 116,0 5411 /dev/snd/controlC0
xpdf.bin 12356 nishita 79r CHR 116,33 5261 /dev/snd/timer
xpdf.bin 12356 nishita 80u CHR 116,16 5391 /dev/snd/pcmC0D0p
xpdf.bin 12356 nishita 81u CHR 116,0 5411 /dev/snd/controlC0
xpdf.bin 22504 nishita 79r CHR 116,33 5261 /dev/snd/timer
xpdf.bin 22504 nishita 80u CHR 116,16 5391 /dev/snd/pcmC0D0p
xpdf.bin 22504 nishita 81u CHR 116,0 5411 /dev/snd/controlC0

I can get the sound back by closing all the pdf files and restarting
the relevant application, but that is exteremly inconvenient. Is there
any way I can refuse to let xpdf use the sound device? (I can't
imagine what use it is of to xpdf anyway!)

Thanks,
Nishita

Weird! For me xpdf does not seem to use the /dev/snd. I opened a pdf file
using xpdf. After that

sudo lsof | grep snd | grep xpdf

returned nothing. It could be something specific to your configuration. What
is your sound card? Are you using ALSA or something else?

I am using Debian Etch, xpdf 3.0.1, ALSA for soundcard configuration.
