Only hearing through left ear with Festival

hooplea · 11-21-2003, 05:25 PM

I'm running Festival 1.4.3 with RedHat 9.0, and I'm using a Logitech 200 USB Headset/
Microphone, and I'm only getting audio through the left ear. Any suggestions? Thanks.

What about other programs (e.g. xmms)?

I agree with h3pc4t - does this issue occur only with Festival, or with all audio apps? If it's with all of them, it may be the plug isn't fully seated or you've got a bad connection, or it could be that your headset is defective. If the sound works on both sides for all audio applications except Festival, then sorry, I have no idea why that would be. -- J.W.

Thanks for replying. The headset does work with XMMS. I get both left and right ears
with XMMS. Since you suggested trying other programs, I did try Grip and the "CD Player"
program and I couldn't get any audio in either ear with those programs. I think I tried once
to check the Logitech website to see if there was a Linux driver for this headset, but I
couldn't find anything. This headset defnitely was detected by linux at startup and I configured it.

Thanks for your replies. I was able to fix this problem. It seems the problem was that Festival sends the output to audio as mono by default and this needed to be changed to stereo with the following 2 lines of code added to festival/lib/siteinit.scm

(Parameter.set 'Audio_Method 'Audio_Command)
(Parameter.set 'Audio_Command "sox -t raw -sw -r $SR $FILE -c2 -t ossdsp /dev/dsp")

I now get audio in both ears.

Congratulations hooplea, that's a good piece of detective work; obviously the mono option did not occur to me as a possible cause. -- J.W.
