So, I decided that I don’t want to listen to the default system sound whenever I receive a new email. In Thunderbird, there is a field in “General Preferences” for one to specify a particular sound file to be played when new mail arrives. Easy enough. I chose the file I wanted it to play (went and found a .wav file that was tolerable, as it seems to prefer .wavs), and hit “Play.” Nothin’. Searching around the tubes, I found that PulseAudio was required for this feature. Certainly not, right? Turns out that that is only one option for playing a custom sound on message arrival. A more suitable, much lighter, alternative is to install the enlightened sound daemon (esd). In Gentoo, this is done with:
emerge -av media-sound/esound
That’s all it takes. The esd is also required for many other applications sound playback functionality, so you may already have it installed. 🙂
