Targetes de so externes
Si acostumeu a treballar en un ordinador portàtil, però us falta música d'alta qualitat podeu utilitzar una targeta de so externa per afegir un joc d'altaveus. Aquesta pàgina documenta l'experiència per aconseguir fer-los funcionar satisfactòriament.
Creative USB XFi 5.1 Pro
El Phonon no veu la targeta de so?
probablement tindrà com a mínim una entrada per a àudio intern i és d'esperar la vostra targeta externa.
Funcionen els altaveus?
Now move to the tab, ensure that on the hardware section the correct card and profile is listed from the dropdown menu, and your speakers will be listed below. Clicking on each one will test the output.
Problemes?
Try the following command:
pacmd list-cards
That should give output similar to this:
If that all looks OK, but your speakers still don't work correctly, try this command:
pacmd set-card-profile 2 output:analog-surround-51
This writes directly to the PulseAudio configuration. You may need to reboot, or your could try
pulseaudio -k start-pulseaudio-x11 start-pulseaudio-kde
My Front Center and Sub-Woofer still do not work. It may not be possible to get them to work, as they may depend upon the output from the laptop, which appears in this case to be stereo only. If you think your system is capable of better, copy /etc/pulse/daemon.conf to ~/.pulse/daemon.conf and open it to edit. Find the following line:
enable-lfe-remixing
Uncomment it and change no to yes. If your system has suitable output this will enable the subwoofer. At the same time you may like to set the default-sample-rate to 48000, which many people think gives a better sound. Again you will need to restart PulseAudio or reboot.
Please add any more information you discover.
