My uniden 536hp scanner seems to go into a sleep mode where it is scanning but there is never any audio. adjusting the volume or squelch knob seems to perhaps wake it up and I start receiving transmission again. I'm sure others on this forum can help me solve a problem. Thanks in advance

The SD card can cause all kinds of weird problems. I would suggest changing the card to see if that helps. The firmware could be corrupted also. Also could be dirty contacts on the headphone or speaker jacks causing the speaker to disconnect. Try inserting and removing a plug in both jacks numerous times. You can also listen with headphones.
