Bugtracker is down ->

from main page ->

So, excuse my reporting here.
I can't record with arecord for long periods.
time arecord -f dat -D hw:0,0 | aplay
Recording WAVE 'stdin' : Signed 16 bit Little Endian, Rate 48000 Hz, Stereo
Playing WAVE 'stdin' : Signed 16 bit Little Endian, Rate 48000 Hz, Stereo
real 186m25.375s
user 1m26.204s
sys 0m20.772s
It seems that this bug was also reported there.
https://bugzilla.redhat.com/show_bug.cgi?id=213783
cat /proc/asound/version
Advanced Linux Sound Architecture Driver Version k3.12.9x40-122l. (custom kernel)
arecord --version
arecord: version 1.0.27.1 by Jaroslav Kysela <perex@perex.cz>
I now trying with sox (rec test.wav) to check if sox is ok.
Thank you for reading this!

What architecture (uname -a) and distribution is this? Was your libc and
alsa-lib compiled with LARGEFILE support?

This is the time needed for 2^31 bytes. Stopping recording after that
is a feature because .wav files (as supported by arecord) have a 2 GB
limit. When recording to a file, it would be possible to create
multiple files, but this is not possible with stdout.
Use "-t raw" to avoid the .wav restrictions. (This requires you to
tell aplay about the format.)
Regards,
Clemens
