Re: [alsa-devel] [PATCH 1/2] aplay: Show usage if no parameter is passed

When aplay/arecord are called without any argument the application hangs forever.

Instead of hanging, print the usage and exit.

• if (argc == 1) {

• usage(command);
  

• return 0;
  

• }

It's possible to call it with "aplay < somefile". Better add a check like isatty(fileno(stdin)).
