Description of problem: I have a machine with an internal sound card and an external (usb) sound card. Up until now the internal card has always been #0 and the external #1. As of 2.6.18-1.2849.fc6 this is no longer the case, often (but not always) the external is #0 and the internal is #1. Version-Release number of selected component (if applicable): kernel-2.6.18-1.2849.fc6@x86_64 How reproducible: Every time. Steps to Reproduce: 1. Reboot 2. Check sound card ordering (eg. with alsamixer) Actual results: The sound cards are in a different order on a random basis. Expected results: Internal sound card is #0 and external usb is #1. Additional info: This works perfectly well up to and including kernel-2.6.18-1.2798.fc6@x86_64. Internal sound card is: 00:11.5 Multimedia audio controller: VIA Technologies, Inc. VT8233/A/8235/8237 A C97 Audio Controller (rev 60) Subsystem: Giga-byte Technology GA-7VAX Onboard Audio (Realtek ALC650) USB sound card is: Bus 001 Device 008: ID 041e:3040 Creative Technology, Ltd iProduct 2 SB Live! 24-bit External
I've just upgraded another machine to FC6 and this has gained random soundcard ordering too. Same type of external soundcard, completely different motherboard: 00:06.0 Multimedia audio controller: nVidia Corporation nForce3 250Gb AC'97 Audi o Controller (rev a1) Subsystem: nVidia Corporation Unknown device 0c11 Again the only workaround is to run an old kernel. Any better suggestions on this one?
I just happened across this bug. Has this behavior changed with newer kernels? If not, have you tried forcing the ordering by putting things in /etc/modprobe.conf (or /etc/modprobe.d/*) like such? alias snd-card-0 snd-ens1371 alias snd-card-1 snd-es18xx Replace with the appropriate drivers. (Assuming, of course, the two devices don't use the same driver.)
The latest kernels (2.6.20 onwards) seem to fairly consistently get the external usb sound card as number 0 and the onboard as card 1, no idea why. Adding the lines you suggest makes no difference at all: alias snd-card-0 snd-via82xx alias snd-card-1 snd_usb_audio
(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 http://fedoraproject.org/wiki/KernelBugTriage I am CC'ing myself to this bug, however this version of Fedora is no longer maintained.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!
Per the previous comment in this bug, I am closing it as INSUFFICIENT_DATA, since no information has been lodged for over 30 days. Please re-open this bug or file a new one if you can provide the requested data, and thanks for filing the original report!
