Subject: Lost dB volumes on USB headset between 2.6.38 and 3.0
Date: Tue, 09 Aug 2011 11:52:33 +0200 [thread overview]

Hmm, I and Colin Guthrie have found a regression between kernels 2.6.38
and 3.0.
When running "amixer -D hw:handset" for this device under 2.6.38, the
attached file is returned. Under 3.0, the dB information is missing.
This can't be intentional, can it?
