Title:
[SB-XFi - Creative X-Fi, playback] Sound is distorted -- (Echo with
garble)
Status in “alsa-driver” package in Ubuntu:
Confirmed
Bug description:
This happens in many applications, but most often happens when using
Orca Screen Reader. The sound will be fine for a moment then start
echoing with distortion.
For instance, the "Welcome to Orca" will say: "We We Wefds
Wefdsalcome t t t05432o O Ordsa ORcadsa ORca fssgdsgdfas", where
random characters are the garble. It is important to note that this
is compressed into near the original time-frame of the original sound,
so it is near impossible to pick out what is being heard.
When this happens, although it seems certain conditions trigger it, it
is system wide. Everything will have that horribly distorted echo.
