soundcard

yesterday i bought a sound card, but the kernel does not recognize it as well. how to recognize my soundcard? thank you

What make and brand of sound card is it?

thank you for reply, my soundcard is asus xonar essence stx sound

The first step is to see if the card is recognized in your system and check the volume levels. If you use KDE, there is a volume icon on the task bar. Click on it. Raise the volume to the maximum. You should also see a Mixer button as part of the volume icon. Click on it. Raise the volume levels of all the different areas - Master, Center, PCM, Digital, etc to maximum. Now see if you can hear your sound card when you play a file.
If this does not work, go to Settings - System Settings - Hardware - Multimedia - Phonon and see if your device is listed. You can test the various devices and change which is the default.
Try this and report back.

well … first. I use cldg 11:09. I tried the volume control was no sound, any mixer I’ve tried to maximize. and this is a list of my hardware, does not seem to read well
