Record audio not working on SoaS

[walter]

Record-60 seems to work on SoaS (on a Classmate PC) except that the video and audio recordings are silent. Sample ogg files are attached. (Nothing of interest in the logs)

SoaS mutes capture channels by default thus check your alsamixer
or try Record-62 - it unmutes/set-to-max at starting
and feel free to reopen ticket if its not volume issue

[CarolineM]

How do I do this?

check your alsamixer
or try Record-62

[walter]

You can run alsamixer from Terminal

You can download Record-62 here:

i've already checked the alsamixer, and downloaded the last version of Record, and the problem still there, both, video and audio recordings are mute.

could you post Record logs

and try this:
gst-launch-0.10 alsasrc ! queue ! wavenc ! filesink location=foo.wav
mute foo.wav should mean that its not Record problem but something in your environment

Indeed, i got a mute foo.wav file, so, where can i start looking for the problem?

check alsamixer again:
$ alsamixer -V capture

if you are using pulseaudio(SoaS does it by default), use:
$ alsamixer -c 0 -V capture

and enable all channels(by <Space> key), maybe you'll have to switch to proper input sources for some channels(internal_mic/docking_station_mic/mix/etc)
and for example on my notebook with HDA Intel sound card I had to increase level of "Digital" channel

Thanks a lot!, that fixes the problem! But, if I restart the machine, the problem is there again.
Is there a way to make a script or something like that?

Sorry, this question is very distro specific(but in my mind every distro sould store levels of alsa channels on shutdown/reboot).

At least on my box Gentoo stores all levels and restores them on startup.

All distros do this AFAIK. What I suspect is that the overlay is not working, so changes to the main filesystem aren't persisting. Can we verify this?
