Alternative to arduino

Is there an alternatives for Arduino with more Volts. I need some board with more voltage.

Instead of asking a question, try just stating your final objective and let us decide what you
need to know.

More volts...

'Final objective' means just that.
What are you trying to do ? (not what you need to do it)
WHY are you asking this question ?
Is there some reason you are not telling us what you are trying to accomplish ? (more volts is meaningless without an application.
WHAT IS YOUR APPLICATION ? (is that clear enough ?)(beside that fact that 'more' is relative. you have not quantified anything.)

How many Volts?

Look, your answer was in answer #1, from DVDdoug.

Arduino does not have an an anlog output, and especially not one that is fast enough for audio output. You cannot just play audio with an Arduino.
You can use an Arduino to control other audio equipment, but the Arduino cannot do it. It is like asking "How do I print with a Ryzen CPU". You can't. You can attach a mainboard, and RAM, and connect a printer to the mainboard, and that printer will print according to the control signals of the CPU.
You can connect the Arduino to a an MP3 decoder and a sound chip with a fast analog output, and you can connect that to an audio amplifier, and that to speakers, and then the Arduino can control the sound output, but ist is just a small, and not very central part of the sound output.

Post your project objective:
FYI : playing music in headphones with arduino directly is not possible.
You can perhaps use an arduino to control audio equipment but an arduino controlling a DAC connected to a preamp connected to the LINE IN of any stereo or other audio product will play music.

If you want to build a sound generation circuit using an arduino you need to generate a standard Line OUT
audio signal and then just plug that into any stereo , be it car stereo or home stereo.
Most likely a Midi circuit would be your best bet.
