[Bug 45167] snd_hda: Default mixer channel is PCM instead of Front

[John Dong]

Public bug reported:

I have an Acer Aspire 5670 laptop with the Intel HDA sound chipset. By
default, the first mixer channel shown is "PCM" and the second is
"Front". In reality, "Front" controls the speaker volume. Even with PCM
set on lowest (PCM channel has no 'mute' option), slight sound is still
outputted. Only setting Front to a low level (or off) directly controls
output levels properly (both via laptop speakers and headphones).


Therefore, "Front" should be the default/master channel, while PCM is a secondary mixer.

** Affects: linux-source-2.6.15 (Ubuntu)
       Severity: Wishlist
       Priority: (none set)
         Status: Confirmed
