Using Multiple Sound Cards

[Peter Torpey]

Paul,

 

Thanks - Your suggestion worked well.

 

The only issue was that I had to guess at which was the correct sound card.
Instead of listing the devices by name (i.e., "Sb Live", "EMU 0202", etc.),
I was presented with a combo saying

USB

external

ichen

PulseAudio

 

USB seemed to be selected (this must have been my EMU 0202 USB device), so I
switched to "external" and sound came out of my SB Live USB device.

 

Thanks again.

Assuming you're not using pulseaudio (which is the default for an accessible
install of Ubuntu),

open gnome-terminal and type

sudo apt-get install asoundconf-gtk

This will add a "Default Sound Card" option to your System > Preferences
menu.

In there is a combo box for picking the card you want to use.  I imagine
Orca will speak through the default card.  Might take a reboot.

I had a strange experience with my sound devices when installing Ubuntu with
Orca.  Also, I have a question on how to have Orca come out of a particular
sound device.

 

First, here is my (slightly unusual) setup:

I have Windows XP Pro installed, and Ubuntu installed on a separate
partition

I have an internal, built-in sound chip, as part of my desktop.  I don't use
this much.

I have an EMU 0202 USB sound device which I generally use for music editing
and creation.

I have a SoundBlaster Live 24-bit USB device which I use for speech output
from JAWS using Windows

 

What went well:

I installed Ubuntu using Orca, and speech came out of the internal sound
card of my desktop computer.  No problems.

 

What went strangely:

After installing Ubuntu, I restarted the computer in Ubuntu and logged into
my account.

Surprisingly, Orca speech came out of my EMU 0202 sound device (although the
quality seems rather distorted).

 

Questions:

 How did this happen that Orca spoke from my internal built-in sound chip
during install and then suddenly switched to my external sound device after
a restart and logging in?

How do I make Orca come out of a specific sound device?  For example, I
would like Orca speech to come out of my SB Live device.  Are there Orca
settings for selecting the output sound device?

Thanks.
