no output digital audio on asus k8v se deluxe
Last modified: 2015-01-04 17:27:01 EST
Description of problem: Version-Release number of selected component (if applicable): How reproducible: Steps to Reproduce: 1. Digital audio (both coax and optical) doesn't work in FC5 x86_64 on asus k8v se deluxe. Used to work in FC4 x86_64, but only relatively late (after a kernel upgrade, IIRC). 2. 3. Actual results: Zilch. Zero. Nada. Expected results: Light on optical output, signal on coax. Additional info:
A new kernel update has been released (Version: 2.6.18-1.2200.fc5) based upon a new upstream kernel release. Please retest against this new kernel, as a large number of patches go into each upstream release, possibly including changes that may address this problem. This bug has been placed in NEEDINFO state. Due to the large volume of inactive bugs in bugzilla, if this bug is still in this state in two weeks time, it will be closed. Should this bug still be relevant after this period, the reporter can reopen the bug at any time. Any other users on the Cc: list of this bug can request that the bug be reopened by adding a comment to the bug. In the last few updates, some users upgrading from FC4->FC5 have reported that installing a kernel update has left their systems unbootable. If you have been affected by this problem please check you only have one version of device-mapper & lvm2 installed. See bug 207474 for further details. If this bug is a problem preventing you from installing the release this version is filed against, please see bug 169613. If this bug has been fixed, but you are now experiencing a different problem, please file a separate bug for the new problem. Thank you.
Since I've switched to Ubuntu I was able to reproduce the bug there on 2.6.15-27-amd64-generic. The workaround involved changing some input state with alsamixer (quite counterintuitively, pulling them down to zero), and saving the result with "alsactl store". I presume by rights this bug should be opened with the ALSA people. Since my FC5 setup has been hosed by an update and I've switched to Ubuntu, I can't verify whether this workaround would work with FC5/FC6.
yeah, given that you've seen it across two different distros, that pretty much rules out userspace differences. I agree with your assessment that reporting to the alsa project bugtracker may be the best way to resolve this.
