    Our forum policy is one post per problem. Do you have 2 problems? If so, what is the problem? No sound? No wireless connection? Unhappy with your mixer options?

    If using KDE4, note in kmix you can go to a menu item (channels) and add more mixer controls.

    OK, please explain the problem. Please answer my questions.

    Do you have ANY sound in your speakers from ANY application?

    Do you have ANY sound in your headphones, from ANY application?

    Please Note, when testing if you have sound, please copy and paste the following speaker-test into a Gnome terminal or a kde konsole:

    speaker-test -Dplug:front -c2 -l5 -twav

    Note Linux is case sensitive, and D is not the same as d. To stop the above test, while the konsole/xterm has the mouse focus, press <CTRL><C> on the keyboard. Note you should check your mixer settings (kmix if using KDE, and alsamixer if using Gnome) to ensure that PCM and Master Volume are set around 95%. Once you have basic sound established you can back off to lower volume levels. Note the test for surround sound is different.

    If that test yields errors (and its not uncommon to get errors there), try instead this more simple test:
    speaker-test -c2 -l5 -twav
    You should hear a female voice saying 'FRONT LEFT', 'FRONT RIGHT' five times. Its quite common that one of those speaker tests will work and one will NOT work, so don't be distressed if that is the case. IF that test gives sound, stop now, post that the sound test gives sound, and we will look at other possible causes for your applications not giving you the sound you want (such as missing codecs, using the wrong packaged version ... etc ... ).

    Or alternatively, for testing the simple playback, use aplay program. Prepare a WAV file and simply run like:
    Code:
    aplay -vv somefile.wav
    With the option -vv, aplay shows the verbose information of the PCM device, and a VU-peak meter during playing the file.

    Try those speaker-tests as both a regular user, and also with root permissions. If you have a headset, try with your headset plugged in, and also with your headset not plugged in (for speakers).

    Hmmm ... typically most Linux (and not just openSUSE) users want the EXACT opposite. They want speaker volume muted when headphones are plugged in. Hence alsa is set up to do exactly that (mute headphones upon speakers being plugged in).

    I could be wrong, but I think what he's saying is that he wants to have
    two simultaneous sound outputs going. The first would be music, being
    played through the speakers. The second would be a text-to-speech
    application playing through the headphones.

    This actually seems like an ideal use for PulseAudio. It should be able
    to take the two sound producing applications and route one to the
    speakers while routing the other to the headphones.

    I do not know how to create such a setup myself.

    If there is a way to do this, I suspect there are two possible ways to go about it.
    • one might by using pulse audio, as you note; or
    • another might be by the creation of a custom .asoundrc file in one's /home/username directory

    In either case, this is beyond my current knowledge.

    User kc0hwa could try asking this question on IRC channel freenode #alsa . There are sound guru's who hang out there, and its possible one of them might know how. Typically one has to ask for help at many different times of the day, in order to obtain a good response, as the people who join that chat channel are from all around the world. I typically use the program xchat for accessing IRC chat.
