So, there are two options - backport the recent ALSA Audio USB driver or backport the above changes to the RHEL 6 kernel.
There is bunch of dB related changes in the recent ALSA USB driver: Unfortunately, many USB devices have trouble to follow these specs. This information is obtained from the driver which computes these values according the USB specification. The 0% means 0dB for the user space mixer layer. Playback channels: Front Left - Front Rightįront Left: Playback 0 įront Right: Playback 0 According dump:Ĭapabilities: pvolume pswitch pswitch-joined The command tries to set the Speaker volume to sane -20dB value if Master controls are not present and to 0dB if Master is present. This command in called from the udev rules. The Speaker volume and Master volume should be initialized/restored using 'alsactl restore 1' (1 is the card number to be initialized).

If you install pavumixer (from Fedora), you can configure these volume levels as well.Īttached is the output of alsa-info from an affected system. You could save the settings with alsactl store, but this doesn't help. The default volume should be configured to a reasonable level.Ĭhanging /etc/pulse/default.pa to flat-volumes = no doesn't fix this.
Look at alsamixer -Dhw -c1 and raise the volume up Attempt to use a soft phone application such as Twinkle and see how low your audio isģ.
Version-Release number of selected component (if applicable):Ģ. This, of course, does not persist across reboots. The only way to get the volume up is to use alsamixer -Dhw -c1 and raise the master volume from there. gnome-sound-properties seems unable to raise this volume effectively higher. If you attach a USB headset, PulseAudio gives it a very low volume.
