That's a case for the ALSA mixer initialization database. Please run "alsactl init 0". This should put your card back into initial default (and too loud) setup. Then, please use gnome-volume-control to configure a good volume and paste the output of "amixer -c0" and "alsa-info.sh --no-upload" here. This will allow us to add an entry for your card to the default mixer initialization database so that the volume will be configured sensibly by default in the future. > 2. Additionally, while ramping volume, only on every 3rd or 4th notch of the > volume control does the audio play through cleanly. Those other spots, the > audio goes into full distortion. Sounds like bug 530049. And is fixed. You can temporarily fix this by setting the env var PULSE_NO_SIMD=1 when running PA. Created attachment 367797 [details]
alsa-info.sh --no-upload

alsactl init 0
Unknown hardware: "NFORCE" "Realtek ALC650E" "AC97a:414c4722" "0x1043" "0x8095"
Hardware is initialized using a guess method
See attachment for log after setting gnome-volume-control to a decent level 21%, and
This worked well with a pair of headphones, and an external amplifier turned up fairly high, to allow for gnome-volume-control to allow setting of the level up to close to output level.
The same level sent into a Sony TV VGA + audio IP comes through at a much lower level, and the TV needs to be turned up to 7-% for this same level to be reasonable.
2. pulseaudio -k && PULSE_NO_SIMD=1 pulseaudio
solves the distorted attenuation that was previously occurring through most steps of the volume range. cat /proc/cpuinfo:

This bug appears to have been reported against 'rawhide' during the Fedora 12 development cycle. Changing version to '12'. More information and reason for this action is here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping This message is a reminder that Fedora 12 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 12. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '12'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 12's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 12 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora please change the 'version' of this bug to the applicable version. If you are unable to change the version, please add a comment here and someone will do it for you. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping Fedora 12 changed to end-of-life (EOL) status on 2010-12-02. Fedora 12 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. Thank you for reporting this bug and we are sorry it could not be fixed. |
