Hi eowyn224,
Thank you for using the Apple Support Communities! It sounds as you are experiencing a few issues with your iPod. To start, for the issue with the volume we would recommend the steps from the article below which can help:
If you hear no sound or distorted sound from your iPhone, iPad, or iPod touch speaker
1. Remove all screen protectors, films, or cases from your device.
2. Check the speaker opening to see if it's blocked or dirty. On iPhone only, make sure that the receiver isn't blocked or dirty.
3. If necessary, clean the speaker or receiver opening with a small, soft-bristled brush. Make sure that the brush is clean and dry.
4. Go to Settings > Sounds (or Settings > Sounds & Haptics), and drag the Ringer and Alerts slider back and forth a few times. If you don't hear any sound, or if your speaker button on the Ringer and Alerts slider is dimmed, your speaker might need service.
Additionally, the guidance from the next resource below can help if your iPod is running slowly. Please keep in mind although the article is titled for iPhone and iPad, the steps can also apply for your iPod:
If your iPhone or iPad is running slow
Hope this helps!
Have a great day.
