Description Jim Pingle 2001-07-30 02:00:01 UTC

Using an AudioPCI ES1373-A sound card that is built onto the 
motherboard, using mixer on pcm works oddly. 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.
