Maybe bass and treble settings OR the volume control IC has gone bad. Basically, all analog signals processed by DAC fed from DSP will enter this IC for bass and treble control. If it is bad, no bass and treble control can get. You should bear in mind that the setting of bass and treble is good before checking the volume control IC.

Most laptop sound card do not have a setting for bass and treble.
You can use external powered speakers that have bass and treble settings and connect these speakers to the headphone socket on your laptop.

There are no hard and fast rules for setting Bass, Midrange and Treble on your radio. Depending on the type of music you are listening to with your radio, it can / will determine your sound settings. To attempt to set the sound settings on your radio, select the sound settings and set all of them to 0. ( Bass,mid,treble ), then start playing your usual music. With the music playing move the treble setting in single incriments 1,2,3,4 and so. A comfortable setting is usually a 5 out of a total number of 6. Then move over to Midrange and repeat process. A 4-5 out of 6 is usually comfortable. Finally comes the Bass. You do not want to overpower your speakers with too much bass as this will damage them over time. Repeat the usual process and listen carfully for any baffling or distortion as you move through the numbers. A comfortable bass setting is usually 2-4 out of 6. Again I must stress that there is no hard and fast rule for settings. It boils down to the type of music, and what your ears tells you sounds good. What sounds good to me might not be enough for you, or vice versa. I hope this helps! Cheers!

You should check the Direct button is pressed or not.
In Direct mode, it by passes the treble and bass circuitry so you will not hear any difference even if you turn it.

Dont assume because you have set the bass and treble options for your radio that they will work for your cd, press the source button until you come to cd and then set your bass and treble again, hope this works
