No Coax digital out with SB Live! and 2.6.15

No Coax digital out with SB Live! and 2.6.15

[Tino Keitel]

Hi folks,

since I upgraded to 2.6.15, the Coax digital output of my SB Live!
stays silent. Analog output works. After reverting to 2.6.14.3 the
digital output works again. Does anyone have a solution for this or at
least the same problem?

Regards,
Tino

I just tried alsa-driver 1.0.11-rc2 and now the digital out works again.

alsa-driver 1.0.10 works, too.

Are you sure it was not a mixer settings issue?

If you can confirm that this is a regression try to narrow it down by
code inspection or binary search by date with ALSA CVS it can be fixed
for 2.6.15.x.

I booted with the 2.6.15 driver and got a silent digital out, like
reported. The headphone which is plugged into the analog output gives
sound.

If I load the 1.0.10 driver, sound works in xmms. If I unload it and
reload the original 2.6.15 driver, sound still works. If I reboot with
the original 2.6.15 driver, the digital out is silent again, while the
analog output works.

However, if I now chose a specific output device in xmms, hw:0,2,
instead of the default device, digital out gives sound. With the 1.0.10
driver, this hw:0,2 device stays completely silent (digital and
analog). With this version, the hw:0,0 device (which seems to be the
default) gives analog and digital sound.

So IMHO this mixup of the devices is a regression, since it breaks
existing setups and is also fixed in newer versions. It would be nice
the see a fix for this in 2.6.15.x.

The solution looks more simple: just removing and reloading the
original snd-emu10k1 module reorders the devices so that the default
device gives sound on the digital output. The driver is blacklisted in
udev and loaded at boot time in /etc/modules, so the module-init-tools
initscript will load them. However, I have no idea why it behaves
different if loaded at boot time than when reloaded later.
