[Bug 227504] New: Siemens M34 USB occasionally stops soundcard
https://bugzilla.novell.com/show_bug.cgi?id=227504 Summary: Siemens M34 USB occasionally stops soundcard Product: openSUSE 10.2 Version: Final Platform: 32bit OS/Version: Other Status: NEW Severity: Normal Priority: P5 - None Component: Sound AssignedTo: tiwai@novell.com ReportedBy: Olaf.Amm@fmi.fi QAContact: qa@suse.de I use a Siemens M34 USB adapter for VoIP calls (unfortunately not supported by Linux, but my machine is a Windows/Linux dual boot), and a Soundblaster sound card. Usually, even though the M34 USB is not useable under Linux, things work fine and the sound card is working normally. However, every 5th login or so, apparently randomly SuSE Linux recognises that M34USB adapter as the "sound card", so the actual Soundblaster card is disabled, and sound doesn't work. I think SuSE should not assign an USB device that it cannot fully recognize as a sound card. - Is there any fix/workaround for this? -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.

For avoiding the auto-loading of USB-audio module, add snd-usb-audio to /etc/modprobe.d/blacklist. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.

Changing users and re-login doesn't change the status regarding this issue. Thanks for the info about "blacklist", I'll try it and report here later whether or not it has completely stopped the problem. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.
https://bugzilla.novell.com/show_bug.cgi?id=227504 ------- Comment #3 from tiwai@novell.com 2006-12-19 08:48 MST ------- OK, then this is likely because of the order of loaded modules. You can specify the device order statically by adding options snd-usb-audio index=1 to /etc/modprobe.d/sound file. But, in your case, the usb-audio device doesn't work anyway, so blacklisting might be easier. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.
https://bugzilla.novell.com/show_bug.cgi?id=227504 ------- Comment #4 from Olaf.Amm@fmi.fi 2006-12-22 12:01 MST ------- Ok, the second method: options snd-usb-audio index=1 to /etc/modprobe.d/sound file did *not* work (same sympton as described just happened again, in spite of this line). Now I'll try blacklisting options snd-usb-audio. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.
https://bugzilla.novell.com/show_bug.cgi?id=227504 ------- Comment #5 from Olaf.Amm@fmi.fi 2007-01-07 09:24 MST ------- After two weeks of putting the USB-audio module to "blacklist", the error has not appeared again, so it seems that this fixes it (of course on the cost that USB-audio doesn't work). As written in comment #4, specifying the device order did *not* solve the problem, though. Best would of course be if it would just recognise the USB devices correctly, and not let them interfere with the sound card... -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.

Could you check whether the index module option is really passed correctly by checking /sys/module/snd_usb_audio/parameters/index ? -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.

Interestingly, there is still no directory snd_usb_audio under /sys/module/ at all. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.
