I'm having some problems with alsa since 1.0.6a. Previously I just had the later versions masked, but now various kde packages require the latest alsa, so I'm having to tackle it now. ALSA seems to start normally, however I get this error in dmesg: EMU10K1X: probe of 0000:00:09.0 failed with error -16. I also get this error when running alsamixer: alsamixer: function snd_ctl_open failed for default: No such device And similar ones in other alsa programs. Again, 1.0.6a runs fine, 1.0.7 and above do not. I've taken a look at the code and it seems that the error is vaguely interrupt related, but I could not find the code that produces error -16. I've swapped interrupts around and disabled non-essential devices (usb, serial, parallel ports, removed network cards and sound cards - although that last one proved slightly less than helpful :) I've changed from having my bios manage irq's to having the OS handle them with zero success. I've looked around for that error code in google for the last few weeks - since the release of 1.0.7 with limited success. Nothing relevant to my situation.

Again, it works perfectly fine in 1.0.6a, the problems only appear in later versions. Reproducible: Always Steps to Reproduce: 1. Install any version of alsa > 1.0.6a 2. Start alsa 3. Watch in horror as nothing actually works Actual Results: [see details] Expected Results: Started alsa

Please report this problem on alsa's bug tracker.
Reported in alsa's bug tracker at https://bugtrack.alsa-project.org/alsa-bug/view.php?id=752 Also, it is alsa 1.0.5a that works correctly. 1.0.6a and later fail.
