I'm the original reporter and I'm willing to test potential fixes. Currently under work. Note that I did already report a bug before you did : https://bugzilla.redhat.com/show_bug.cgi?id=499228 Maybe we could merge both ? Magic !!!!!!!!!! It WORKS !!! Thanks so much :) --------------------------------------- Fix --------------------------------------- 1) Create a file named /etc/modprobe.d/audio.conf with one line containing : options snd-hda-intel model=acer 2) Download ftp://ftp.suse.com/pub/people/tiwai/misc/hda-verb-0.3.tar.gz uncompress it anywhere, cd to the place you uncompressed it, run make as root, then ./hda-verb /dev/snd/hwC0D0 0x15 SET_EAPD_BTLENABLE 2 3) Play a sound, it should work :) But ;) always a but... - The headphones are not recognised and even when I do check the check box in volume control under parameters, it always plays on the laptop's 5.1 system. - Which one appear to be working on only 2 speakers (disabling LFE, centre and surround doesn't change anything while playing 5.1 AC3 files) Before I did it, I had already done some modification like : - adding my user to the pulse-access and pulse-rt group - giving authorisations to pulseaudio real-time scheduling and High priority scheduling - adding 6ch to pulse audio with a line in /home/your_user_name/.pulse/daemon.conf : default-sample-channels = 6 you can add 6 channels for all users by adding the line default-sample-channels = 6 in /etc/pulse/daemon.conf instead of your home directory I don't know wher to put "hda-verb /dev/snd/hwC0D0 0x15 SET_EAPD_BTLENABLE 2" so that it does it at boot time automatically. *** Bug 499228 has been marked as a duplicate of this bug. *** mtam: you can stick it in /etc/rc.local , just that command on a line in that file. All commands in /etc/rc.local are run as root during boot up. Thanks Adam, thanks Lennart, for the 5.1 channels and jack not working, I did google it to but the above tricks don't work (with totem, vlc or whatever) adding 6ch to pulse audio with "default-sample-channels = 6" in /home/your_user_name/.pulse/daemon.conf only make the volume control show 6 channels, but the new channels don't work... even when trying to configure them with "alsamixer -c0" - adding my user to the pulse-access and pulse-rt group - and giving authorisations to pulseaudio real-time scheduling and High priority scheduling remove sound crackling, I think it should be activated by default on Fedora11. Maybe should I make a new bug report ? mtam: for the surround sound stuff, that problem is part of this report. You're not going to be able to fix it by playing with the Pulse settings. The problem is that the partial workaround you're using isn't enough to get the second and third pairs of outputs actually working at the raw ALSA driver level, so changing settings at a higher level (as Pulse is) won't fix it. We need to come up with a full fix at the ALSA driver level to enable the full set of analog outputs. And by 'we' I mean 'Jaroslav' =) For the crackling, it's possible that will require a second report, but it may also go away once we have this hardware properly supported at the ALSA level, so hang tight for now. I stay tuned :) For the crackling, I already fixed it by adding my user to the pulse-access and pulse-rt group and giving authorisations to pulseaudio real-time scheduling and High priority scheduling. I did write it so that this bug report fix as much things as possible about sound in Fedora. In fact, I did it before having sound, but when I tried to remove it, the sound started crackling, and when I did it back, sound worked properly again. So I think it's important to make all users part of pule-* groups and to give rights to those schedulding things by default on Fedora. Sorry for my bad English. I can't wait to have headphones and 5.1 :) Thanks again This bug appears to have been reported against 'rawhide' during the Fedora 11 development cycle. Changing version to '11'. More information and reason for this action is here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping a brother of mine using F11 on Acer Aspire 8920G, he have tested "hda-verb /dev/snd/hwC0D0 0x15 SET_EAPD_BTLENABLE 2" and it worked for him. This message is a reminder that Fedora 11 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 11. 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 '11'. 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 11'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 11 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 11 changed to end-of-life (EOL) status on 2010-06-25. Fedora 11 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. If you cannot get any sound on Acer Aspire 8920g laptop then check your laptop setting that the audio is enabled or not because sometimes it may in disable mode.
