Sound Problems

• Yagitlk/Firefox freezing when speaking or when pressing 'stop' (#1)
• Other application unable to use the sound system while Yagitalk is in use

Reason

This is due to Linux legacy OSS sound layer/driver not supporting mixing, which result in sound output completely locked by another application already using the sound output file /dev/dsp. Yagitalk uses the Java sampled sound API and Sun's Java sampled implementation relies on hardware/driver level mixing.

Solution

Wrong settings of your sound system on Linux may result in Firefox freezing and/or disabled audio output for other applications when Yagitalk is running (this is not specific to Yagitalk, but also happens with Flash plugin audio output in Firefox). If you encounter this problem, try to configure your sound system to use Alsa and enable oss-emulation. Set the FIREFOX_DSP="aoss" parameter in your $HOME/.mozilla/firefox/rc or /etc/firefox/firefoxrc (on Debian/Ubuntu) to enable
