First of all, patch is not included in the alsa git yet. I think it's important to discuss it before.
Example for applying the patch (I tried it with Intrepid and Jaunty; please don't do that if you don't know what's all about): Download attached AlsaUpgrade-1.0.x-rev-1.16.sh script modified for conexant codec (upgrade to alsa 1.0.19; originally it's from here http://ubuntuforums.org/showthread.php?t=1046137). Download above attached patch_conexant.c.patch file. Launch AlsaUpgrade script with option -d (download the packages only): sudo ./AlsaUpgrade-1.0.x-rev-1.16.sh -d Check /var/log/AlsaUpgradeRev-1.16-XXXXXX-XX.XX.log file if there was no problem. Apply the patch: sudo patch /usr/src/Alsa-1.0.19/alsa-driver-1.0.19/alsa-kernel/pci/hda/patch_conexant.c patch_conexant.c.patch If there is no problem launch AlsaUpgrade script with option -i (compilation and installation of packages): sudo ./AlsaUpgrade-1.0.x-rev-1.16.sh -i After that, check /var/log/AlsaUpgradeRev-1.16-XXXXXX-XX.XX.log file if there was no problem. Find out your subsystem id: lspci -vnn | grep -A1 Audio If you don't have subsystem id 17aa:20ac and you think that it could work, include "options snd-hda-intel model=lenovor61i" at /etc/modprobe.d/alsa-base file. Then reboot. Launch alsamixer: F3 - playback controls: Master; PCM; IEC958; IEC958 Default PCM PCM slider ought to be now at 100 with db gain 0.00, so there is no more distorted sound over 0.00 db. F4 - capture controls: Mixer; (Digital?); ExtMic; Input; IntMic Select capture source among Mixer; ExtMic; IntMic by pressing SPACE on it. Input slider: lowest level is best for Mixer, highest level is best for Mics; if you press SPACE on it, you turn off capturing at all. Digital slider: I don't know why it appears, leave it at 50 (db gain 0.00). I have two questions: How to name Mixer and Input slider? (or let it be as it is) Do you want Ext Mic and Int Mic sliders back? (i think it's useless, it does nothing) Thank you for testing. ** Attachment added: "modified AlsaUpgrade script" http://launchpadlibrarian.net/24185669/AlsaUpgrade-1.0.x-rev-1.16.sh -- [regression]snd-hda-intel sound input does not work at all with Conexant CX20549 (Venice) chips https://bugs.launchpad.net/bugs/278648 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
