Bug#571253: aumix does not report/change settings correctly on additional devices
Package: aumix Version: 2.8-21 Severity: important I have two audio devices - an intel onboard and a USB mic in a Logitech webcam. Aumix is unable to adjust any of the volumes on the cam when invoked with the relevant -d argument The behaviour is rather strange. -q reports correctly only one channel - audio with incorrect values. Toggle switch is reported correctly. Volume levels reported are incorrect and cannot be adjusted neither from commandline nor interactive. kmix and other mixer software have no problems. I have observed similar behaviour in the past on other USB audio. I can probably dig out the adapters that show this and reproduce it if need be. -- System Information: Debian Release: 5.0.4 APT prefers stable APT policy: (500, 'stable') Architecture: i386 (i686) Kernel: Linux 2.6.26 (SMP w/1 CPU core; PREEMPT) Locale: LANG=en_GB.UTF-8, LC_CTYPE=en_GB.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/bash Versions of packages aumix depends on: ii libc6 2.7-18lenny2 GNU C Library: Shared libraries ii libgpm2 1.20.4-3.1 General Purpose Mouse - shared lib ii libncurses5 5.7+20081213-1 shared libraries for terminal hand aumix recommends no packages. aumix suggests no packages. -- debconf-show failed -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of unsubscribe.

Bug#571253: aumix does not report/change settings correctly on additional devices
I have two audio devices - an intel onboard and a USB mic in a Logitech webcam. Aumix is unable to adjust any of the volumes on the cam when invoked with the relevant -d argument The behaviour is rather strange. -q reports correctly only one channel - audio with incorrect values. Toggle switch is reported correctly. Volume levels reported are incorrect and cannot be adjusted neither from commandline nor interactive. kmix and other mixer software have no problems. I have observed similar behaviour in the past on other USB audio. I can probably dig out the adapters that show this and reproduce it if need be. Interesting, I can actually reproduce that with my Logitech webcam. However, I don't think aumix is at fault here: if you try alsamixer, you'll notice (or at least I noticed) that the webcam's mixer channels are way less sensitive than normal ones (i.e. I have to keep the down-arrow pressed for a whole second in order to lower the volume by 1%, normally a second is enough to bring it down to almost 0) thus I'm inclined to blame the audio driver. Also, if you change your volume in some other application, aumix doesn't seem to see that change (on your normal sound card, you'll notice that aumix updates its display when you change your mixer levels in another app), and since aumix is highly unaware of what sound card you use, I again blame the driver for not properly exporting its mixer levels through the OSS API (other than most other mixer applications, aumix uses the legacy OSS API instead of ALSA). If you have some time, I would appreciate it if you could see whether this also happens with older kernel releases (eg. the one from stable), in the end I guess we'll have to reassign this one to the kernel people, though. Anyway, thanks for your report. cheers -- Stefan Ott -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of unsubscribe. Trouble? Contact listmas...@lists.debian.org

Oh sorry, I just noticed that you *are* actually using the stable kernel version. Please ignore that request. -- Stefan Ott -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of unsubscribe. Trouble? Contact listmas...@lists.debian.org
