I tried a patch proposed by Takashi and it fixed the problem, however there is a post
Raymond Yau superquad.vortex2 at gmail.com Fri Aug 19 00:55:54 CEST 2011 The patch seem fix the no dB scale problem , however the broken dB test which you added seem redundant as cval->dBmin and cval->dBmax are still zero because error in get_min_max() at build_feature_ctl() and it seem that the valid dBmin and dBMax are calculated by get_min_max() at mixer_ctl_feature_info() on my usb logitech web cam so some more investigation might be required ** Patch added: "usbmixer.patch" https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/820833/+attachment/2290687/+files/usbmixer.patch -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/820833 Title: Logitech USB Headset lost dB volumes when upgrading to Oneiric To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/820833/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
