Only by a fraction of the total power consumption.
Normal audio power levels are from 1/100th of a Watt to 1 Watt. If you run the TV at full volume, you might draw 5 Watts.
Compare 1 Watt (normal volume) with the total power of 100+ Watts and you'll see it doesn't make much difference.

Yes but not as much as you might think.
The small amplifier included in the TV is already powered on and set at a pre set level. When you crank up the volume the amp uses a tiny bit of extra juice to take care of the job.
A tube TV uses most of the power just to generate the picture.
Typically a TV uses anywhere from 115 watts(27in tube) to 615 watts (56in LCD). Your hair dryer uses about 1500 watts of electricity.

Not by enough to make a difference that you would notice in your electric bill.
