alsa-project/alsa-utils pull request #266 was opened from genbtc: bug: lowering volume below 0 causes volume to overflow and spike to 100% volume hurting my ears. to reproduce: when holding down z,x,c to lower the volume, the volume spikes to 100% and then down to 0% over and over background: when volume is already 0 and direction is -1 (lowering volume) - but lower than 0 is impossible the function `set_normalized_volume` @ volume-mapping.c is eventually still called anyway `value = lrint_dir(6000.0 * log10(volume), dir) + max;` and volume is 0, so log10(0) resolves to negative infinity, so value overflows past infinity. 9223372036854775802  my fix: this function `change_volume_relative` function will now skip execution of the set_normalized_playback_volume function when volume is 0 and the dir is -1 TLDR: (stop trying to set a lower volume than 0) Request URL : https://github.com/alsa-project/alsa-utils/pull/266 Patch URL : https://github.com/alsa-project/alsa-utils/pull/266.patch Repository URL: https://github.com/alsa-project/alsa-utils
