Looks like it's due to the indentation error in your YAML file

Volume should be under the spec section

Example YAML i am using

apiVersion: apps/v1
kind: Deployment
metadata:
  labels:
    app: hello-app
  name: hello-app
  namespace: default
spec:
  progressDeadlineSeconds: 600
  replicas: 1
  revisionHistoryLimit: 10
  selector:
    matchLabels:
      app: hello-app
  strategy:
    rollingUpdate:
      maxSurge: 25%
      maxUnavailable: 25%
    type: RollingUpdate
  template:
    metadata:
      creationTimestamp: null
      labels:
        app: hello-app
    spec:
      containers:
      - name: nginx
        image: nginx
        imagePullPolicy: IfNotPresent
        volumeMounts:
          - mountPath: /etc/cert/
            name: foo
          - mountPath: /etc/nginx/conf.d
            name: nginxconf
            readOnly: true
      - image: gcr.io/google-samples/hello-app:1.0
        imagePullPolicy: IfNotPresent
        name: hello-app
        resources: {}
        terminationMessagePath: /dev/termination-log
        terminationMessagePolicy: File
      dnsPolicy: ClusterFirst
      restartPolicy: Always
      schedulerName: default-scheduler
      securityContext: {}
      terminationGracePeriodSeconds: 30 
      volumes:
      - configMap:
          defaultMode: 256
          name: nginxthroughpass
          optional: false
        name: nginxconf
      - name: foo
        secret:
          defaultMode: 420
          items:
          - key: tls.crt
            path: tls.crt
          - key: tls.key
            path: tls.key
          secretName: nginx-prod

Here is a fixed deployment:

apiVersion: apps/v1
kind: Deployment
metadata:
  labels:
    app: my-app
  name: my-app
spec:
  replicas: 1
  selector:
    matchLabels:
      app: my-app
  template:
    metadata:
      labels:
        app: my-app
    spec:
      containers:
      - image: myname/myimage
        name: my-app
        ports:
        - containerPort: 3000
        volumeMounts:
        - name: audio-sources
          mountPath: /usr/share/nginx/html/audioSources
        - name: authors
          mountPath: /usr/share/nginx/html/authors
        - name: covers
          mountPath: /usr/share/nginx/html/covers
      volumes:
      - name: audio-sources
        hostPath:
          path: /home/websites/audioSources
      - name: authors
        hostPath:
          path: /home/websites/authors
      - name: covers
        hostPath:
          path: /home/websites/covers
  1. Volumes should be under spec,same level as containers.
  2. Also, name of audioSource is changed to audio-source.
