Google Talk – Google Talk Video Chat Alternatives

Do you have microphone problems "everywhere", or is it limited to the gtalk plugin?

Also, did you make sure that your microphone isn't muted?

I have wrote this little script according the instructions suggested by @suli8.

If you save it to a file (lets call it apply-googletalk-v4l1-workaround.sh, but can be anything), then you could apply it by:

sudo bash apply-googletalk-v4l1-workaround.sh

This might help in avoiding small mistakes.

#!/bin/bash

plugin_location=/opt/google/talkplugin/GoogleTalkPlugin

mv $plugin_location $plugin_location.real

cat > $plugin_location <<EOF
#!/bin/sh
LD_PRELOAD=/usr/lib/libv4l/v4l1compat.so $plugin_location.real
EOF

chmod +x $plugin_location

killall GoogleTalkPlugin

I have seen in an above comment that the workaround made Google Talk stop working in Gmail. I guess it was because of some small error in executing the steps. Using this script might avoid that error.
