scsrun.log after running Soundcard Detection gui tool
Since the update to kernel-2.6.18-1.2868.fc6 it seems to be working so far (4 out of 4 reboots). Unfortunately the problem still occurs occasionally even with the latest kernel update. (This is a mass-update to all current FC6 kernel bugs in NEW state) Hello, I'm reviewing this bug list as part of the kernel bug triage project, an attempt to isolate current bugs in the Fedora kernel. http://fedoraproject.org/wiki/KernelBugTriage I am CC'ing myself to this bug, however this version of Fedora is no longer maintained. Please attempt to reproduce this bug with a current version of Fedora (presently Fedora 8). If the bug no longer exists, please close the bug or I'll do so in a few days if there is no further information lodged. Thanks for using Fedora! This problem still occurs in Fedora 8. package details: kernel-2.6.23.9-85.fc8 alsa-lib-1.0.15-1.fc8.i386.rpm alsa-utils-1.0.15-1.fc8.i386.rpm Interesting related messages from dmesg: snd_seq_midi_event: Unknown symbol snd_seq_expand_var_event usbcore: registered new interface driver snd-usb-audio cannot find the slot for index 0 (range 0-0), error: -16 EMU10K1_Audigy: probe of 0000:00:0b.0 failed with error -12 Note that these messages only appear for the sessions where this problem occurs. It is still intermittent, with about 50% probability of failing per boot. Please post the contents of /etc/modules.conf. There is probably not an entry in there telling the webcam microphone to use slot 1... Created attachment 292093 [details]
/etc/modprobe.conf
I assume you mean /etc/modprobe.conf. You are correct, there is no entry relating to the webcam microphone. Relevant lines: alias snd-card-0 snd-emu10k1 options snd-card-0 index=0 options snd-emu10k1 index=0 Whose responsibility (i.e. which package) is it to add this setting to /etc/modprobe.conf? Probably none - I would think that the user should configure that, since they are the only ones that know the configuration details of their hardware. Consider a scenario with a typical user, someone's grandmother let's say. She attaches a new webcam to her computer so she can chat with the grandkiddies. She fires up the computer, logs in and decides to listen to some tunes. Much to her sorrow, there is no sound output. Where does she go from here? I think it is unreasonable to expect a typical user to be able to (1) diagnose the cause of this problem, (2) search the web for a long time to find an obscure solution, (3) edit /etc/modprobe.conf and hopefully get the options right. Perhaps there's not a an easy, automatic solution available, but a problem exists none-the less. Some might even dare to call this lack of functionality a bug. Now, what is the best way to fix this? Perhaps whatever detects the available sound devices at boot up could detect which one has the most capabilities (recording *and* playback, vs recording only) and make this the primary sound device (a la the modprobe.conf changes mentioned in previous comments). I'm not intimate with the details of the sound device auto-detection process, i.e. whether this is done by kudzu or something in the kernel, so I'm not sure to which component this bug should apply. This message is a reminder that Fedora 8 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 8. 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 '8'. 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 8'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 8 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 8 changed to end-of-life (EOL) status on 2009-01-07. Fedora 8 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. |
