export class AudioService {
  isAuthenticated = false

  constructor(
    public auth: AuthService,
  ) {

    this.auth.isAuthenticated$.subscribe({
      next: (isAuthenticated) => {
        this.isAuthenticated = isAuthenticated
      },
      error: (msg) => {
        console.log('error')
      }
    })
  }

  test(): void {
    if (this.isAuthenticated) {
      console.log('Is authenticated')
    } else {
