Red Hat Bugzilla – Bug 489437
poor quality microphone recordings in VoIP apps
Last modified: 2009-12-18 03:59:22 EST
Description of problem: On both my FC8 desktop and FC10 laptop (both Intel 82801G soundcards), microphone records are poor quality. Specifically "s" sounds come through staticy. If I use Ekiga or Twinkle, I get the problem, but if I use Skype - it's fine. Under FC8 I don't use pulseaudio - just straight ALSA, but under FC10 I use pulseaudio - so I'm assuming the fact that I have identical problems on both makes this an ALSA problem? I googled around and after much experimentation can duplicate the problem using ALSA tools. arecord sample.wav makes an 8bit, 8000 Hz recording, and contains the "staticy 's'" problem. If I do it again as arecord -f cd sample.wav the recording is 16bit, 44100 Hz and sounds beautiful. Version-Release number of selected component (if applicable): alsa-lib-1.0.16 and alsa-lib-1.0.19. pulseaudio-0.9.14-1.fc10 How reproducible: Steps to Reproduce: 1. start ekiga/twinkle 2. make call 3. listen to recipient says "ewww - what's wrong with your mic?" Actual results: poor quality voice Expected results: should sound better than it does Additional info: Well, it's not codec-related. It smells to me like Skype is exclusively using "high quality" recordings (ie 16bit) whereas ekiga/Twinkle use defaults - and end up with poor 8bit? I can't see any way of making the apps directly do things differently so am at a loss how to fix this. Thanks for any help Jason
This message is a reminder that Fedora 10 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 10. It is Fedora's policy to close all bug reports from releases that are no longer maintained.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 '10'. 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 10'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 10 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 10 changed to end-of-life (EOL) status on 2009-12-17. Fedora 10 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.
