well i have read whole documentation really..but still no luck
situation my microphone works nice with audacity and rec but with xvidcap no.
kmix set, with boosted microphone
if i use
i got nice volume really nice.
if i use rec -d /dev/dsp temp.wav
i got rec soxio: Failed reading `/dev/dsp': unknown file type
if i use audacity i got nice very nice volume and my kmix boost
i have tried to set up xvid cap
where xxx is :
without no luck...
if i check what programs are using with :
lsof /dev/dsp* /dev/audio* /dev/mixer* /dev/snd/*
when i record with "rec" ,sox subprogram, or audacity i get
artsd 6388 user mem CHR 116,16 12057 /dev/snd/pcmC0D0p
artsd 6388 user 9r CHR 116,33 11642 /dev/snd/timer
artsd 6388 user 10u CHR 116,16 12057 /dev/snd/pcmC0D0p
artsd 6388 user 12u CHR 116,0 12099 /dev/snd/controlC0
rec 12639 user mem CHR 116,24 12064 /dev/snd/pcmC0D0c
rec 12639 user 3r CHR 116,33 11642 /dev/snd/timer
rec 12639 user 4u CHR 116,24 12064 /dev/snd/pcmC0D0c
rec 12639 user 5u CHR 116,0 12099 /dev/snd/controlC0
instead with xvidcap
xvidcap 11323 user 8w CHR 14,3 12071 /dev/dsp

the main thing for xvidcap is that it requires oss because that's what ffmpeg does.
All your other apps typically use alsa or even a sound daemon like artsd, esd, pulseaudio. To test your setup with sox do:
sox -t ossdsp /dev/dsp test.wav
Then play that file back.
I cannot really test mic sampling with current svn atm, because I have none with me. But piped audio input works and I cannot test /dev/dsp input from playing back an audio file because I cannot set up the mixer on this stupid intel HDA chipset on this laptop.
Will test with a mic later (perhaps tomorrow).
sox -t ossdsp /dev/dsp test.wav
sox soxio: Failed reading `/dev/dsp': unknown file type `ossdsp'

This means you don't have the oss stuff for sox installed, so none of the sox based tests you did were testing the right stuff. You need a package that is called "libsox-fmt-oss" on Debian or Hardy, or just "libsox-fmt-all". While you're at it, check you have "alsa-oss", too.
well sorry i was missing some sox library now i get audio that audio file but quality and is very bad , volume is very low
yep installed of course that stuff (libsox-fmt-all ) and now i have read your message alsa-oss too but the same result very noise recording and low volume
The current version works fine on my gutsy machine, see: http://www.jarre-de-the.net/computing/capture-sound.avi
Will try the microphone on my hardy laptop, later.
welll i am on kubuntu 8.04 (it doesn't use pulse or other stuff only alsa i think )
what kind of mixer have you used ? Oss mixer ? :S never seen
dunno how to do this with kmix, but on gnome you just open the normal gnome-volume-control, select file->change device and pick the oss device from the list. If there is none there, your alsa oss emulation is not set up correctly (but then I suppose you wouldn't be hearing anything).
on my hardy laptop, recording from the mic works: http://www.jarre-de-the.net/computing/mic-capture-on-hardy.mpeg
recording from audio playback is very low volume: http://www.jarre-de-the.net/computing/pcm-capture-low-on-hardy-w-intel-hda.mpeg
For me, I very much assume this is to do with the way alsa treats my intel hda (no recording tab in oss, no pcm recording channel). I'll research this some more.
well today i lost my data partition -.-'' and i have , yeah i have used every damned recover software without luck, re-installed kubuntu 8.04
(intel alc861-vd with alsadriver )
so this is what i have discovered:
-first i have instelled audacity and i have recorded something lol (set every things to max and I\O alsa default)
amazing recording is very low...
-so i have installed sox and libsox-fmt-all
tried another time and :
Now volume is very nice
i have google another bit (boring a lot)
and i have discoverd kmix has some silly bug (i am not pretty sure anyway )
so my situation is very complicated
i have a way... but it's pretty boring
when i record my video i re-encode with mencoder and this option .... -af volume=30
!!bye and THANK YOU so much for your support!!
well you can select your oss device on your gnome-mix pretty nice but in kmix there is nothing , i will search for something by terminal right now
well i have solved. the problem i think is this . if you select oss like sound system as normal user there is some problem i don't know it seems it's working but it doesn't so i have made:
type in a terminal :
then go on
select OSS (open sound system)
then change in kmix volume's controlls (boost and microphone)
after that it should save oss settings and you can gon another time on
systemssetting (with kdesudo ) and set autodetect
so now i have nive volume with xvid too
and rememeber to go on kmix setting and set unchecked "Restore Volumes on log in"
or you have to do that every time you log in
thank you Karl !!
I would like to add to this troubleshooting. I downloaded xvidcap to take a snippet of a video and the audio isn't working. I do have dev/dsp and dev/audio on the drive. Tried them along with hwC0D0, hwC0D1.
There is no audio (buzzing etc) and no error msg. Just silence.
I'm running Debian 7.0 if that helps.
If anyone knows the file that I should link to under the audio settings, I sure would appreciate it.
