Re: Sound Recoder Error: could not allocate DMA buffer

I wonder if it is a dma/irq conflict with another device in your computer.
Is the news in tact when it records, or does it skip or otherwise seem not
to sound correct?

See /usr/src/linux/Documentation/sound/README.modules.
In brief, there are problems with ISA cards, DMA buffers, and machines
with over 16M of memory.  Adding the option "dmabuf=1" to the sound
module may help.

Sound Recoder Error: could not allocate DMA buffer

[Laurent POIROT]

After several recordings of wav files with wavrec, i have this Sound Recoder
Error: could not allocate DMA buffer that comes out. I have no idea when
this come from. I use a crontab to make a recording from that soundcard for
5 minutes on a wav file and i do that every 30 minutes. It works perfectly
for a while until this error, if you have any idea, please let me know. I
use Linux Redhat 5.2 with a SoundBlaster Pro ISA. Do you think that changing
the sound card would change this problem ?

thanks
