terratec grabby sound problem

terratec grabby sound problem

[moebius]

Bonjour,

I've bought a terratec grabby device but I've experimented some audio 
problems with it
I run an ubuntu karmic (9.10) distri and use mplayer/mencoder to see and 
capture vhs pal stuff.

But, If video works with mplayer/mencoder, sound doesn't
So I run alsamixer -c1 to access grabby capture volume, then when I 
change volume slider a little bit I get an ugly sound very jerky
Then I go to sound préférences of pulsaudio and swith the grabby device 
to off (éteint in french) andb after to analog input and then I get a 
good sound.

I's very strange because with my old pinnacle dvc100 sound works 
immediatly (but this device seems to have problem because sound move 
time to time to an affect like a flanger and then come normal again ; I 
suspect a hardware problem of the device but I cannot be sure because I 
have no microsoft computer to test it).

I've bought this low-cost terratec grabby to do the job but, finally, I 
experiment another problem....I'm trying to grab my vhs since several 
months and I have still no success !

I cannot try to grab my vhs because,even doing things I've mentionned, 
I'm never sure that it works because mencoder encodes but don't show any 
video or sound during it works.


I've seached but found nothing...so I post here.....if someone has an 
idea.....

cordialement,

Re: terratec grabby sound problem

[moebius]

Bonsoir,

I've tried to specify another card (an easy cap), so I do :

rmmod em28xx
modprobe em28xx card=64

In this case, I avoid alsamixer step : I get immediatly the bad sound 
and I just have to shut off and on the terratec grabby in pulseaudio 
control applet to get mplayer working. But no progress with mencoder.

There's really a problem...noone else own a terratec grabby device ?

It's really boring, I have a job to do since a long time nowq, and I 
can't do it ......


cordialement,
