Sound card not working ...............

[Sandeep]

there is no sound in my computer...
When i get into the sndconfig it says....

you don't seem to be running a kernel with modular sound enabled. │
│ (soundcore.o was not found in the module search path). │
│ To use sndconfig, you must be running a kernel with modular │
│ sound, such as the kernel shipped with Debian GNU/Linux or a 2.2 │
│ kernel, and sound must be compiled as modules. │
│

Try opening a terminal and type

modprobe soundcore

does the module load and do you have sound?
What kernel are you running and what soundcard do you use?
