[alsa-devel] alsamixer crashes with SIGFPE

[Florian Faber]

Hi,

there are several spots in alsamixer's mixer_display.c that cause SIGFPE
through division by zero if (max-min) is zero:

bar_height = ((volumes[c] - min) * volume_height + max - min - 1) / (max
- min);

value = ((volumes[0] - min) * 100 + (max - min) / 2) / (max - min);

etc.
