alsa-project/alsa-lib issue #451 was opened from ewtoombs:

Minimal reproduction:

```
#include <alsa/asoundlib.h>
#include <stdbool.h>
int main(int argc, const char **argv)
{
    snd_pcm_t *out;
    assert(snd_pcm_open(&out,
                "default",    // the name of the device being opened
                SND_PCM_STREAM_PLAYBACK, // it is an output stream
                false         // iff nonblocking stream
                ) == 0);
}
```
(Compile with `gcc -o test test.c -lasound`.)

Relevant `lspci`:

`uname`:

I've heard similar artefacts on many different sound cards, though, across many different architectures, always on linux.
One must wait about five minutes in between trials, or the artefact does not occur.

This isn't a minor detail.
The tick is very loud.
It might even damage speakers in a worst case scenario.
