When adjusting the volume of the pcm device, going from 0->100 yields two cycles from low->high. If I type "mixer pcm 50:50" it has the same effect as "mixer pcm 0:0", and "mixer pcm 49:49" is the same as "mixer pcm 100:100". Adjusting the "vol" device works normally from 0->100. >How-To-Repeat: Have a motherboard with: pcm0: <AudioPCI ES1373-A> port 0x1800-0x183f irq 11 at device 12.0 on pci0 Play a (long) audio file. mixer vol 100:100 mixer pcm 0:0 (Silence, as expected) mixer pcm 49:49 (Full volume will be heard) mixer pcm 50:50 (Silence again) mixer pcm 100:100 (Full volume, as expected) The problem should be quite audible. >Fix: >Release-Note: >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
