I am trying to enable an audible terminal bell/beep through the 1/8" mini-rca audio out (headphone jack) on debian wheezy with the rapsberry pi model b. Normal audio works as expected, when playing a shockwave file in Midori with gnash for example.
I turned the Audible bell setting in LXTerminal preferences ON, and tried the following:
$ xkbbell (no sound)
$ xkbbell -dev 0 (X Error of failed request: 146)
$ beep and $ beep -f 500 -l 700 after installing it with apt (no sound)
That said, this is all in an attempt to hear the bell sound triggered by PuTTY, when Action to happen when a bell occurs is set to Make default system alert sound. There is no option, like in the Windows version of PuTTY, to play a custom sound file when a bell occurs.
I've read that running # modprobe snd_hda_intel on other linux machines can redirect sound output intended for the PC speaker (which the raspberry lacks) to ALSA. Running that command tells me that this module is not found. I don't know how to acquire it with apt.
I really hoping someone has some insight...I'm dizzy from Googling!
