speaker-test fails on OMAP3 based boards

Fails on Beagle C4 as well tho in that case it's a matter of no output.

Interesting data point ... the tool seems to be freezing

Beagle Xm fails much like the panda.

Fails currently on Xm and Beagle C4 with the omap3-x11 hwpack and alip from beta2.

Sound only works at Beagle if you use alsamixer to unmute and increate the volume of the other available options.

After setting up with alsamixer I'm able to use speaker-test.

On PandaBoard speaker-test was working with HDMI Audio.

Removed panda from bug name because of Marcin's feedback.

still present on beagle C using current daily 0706 daily snapshot + alip image

While I don't have an HDMI sound sink, using alsamixer I can't see the analogue output or hear anything on it. It is currently unsupported?

Sorry, forgot to say I am using a Panda board.

on 11.07 alip RC on beagle Xm this continues to fail exactly as was reported some time ago.

alasmixer won't run for me. I ran it with strace and I think this is the problem:

 open("/dev/snd/controlC0", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file or directory)

The only thing under /dev/snd for me is timer.

this is also broken on Overo.

still broke with with today's (2011-08-22) snapshot. This looks like a kernel issue to me, so I wonder if we have this bug assigned to the proper team? Seems like linaro-linux-omap3 is probably better.

Here's my kernel info:

  Linux linaro-nano 3.0.0-1003-linaro-omap #4~ppa~natty-Ubuntu SMP PREEMPT Mon Aug 8 21:53:39 UTC 2011 armv7l armv7l armv7l GNU/Linux

I've found the cause of this problem. During the change to the 3.0 kernels we changed how the sound drivers were build for OMAP. Previously they were built-ins, they are now built as modules:

 CONFIG_SND_OMAP_SOC
 CONFIG_SND_OMAP_SOC_OVERO
 etc

I thought I'd be clever and just load the module. However, that still didn't fix the issue. I then built my own kernel with OMAP sound selected as built-ins rather than modules and sound started working again.

So there's still some issue with OMAP sound not working as modules. However, for the time being I think we should just make these built-ins so that OMAP3 sound will work again. I've attached a diff of my original .config and my new .config that fixes the issue.

I get no errors using kernel linux-linaro-3.0-2011.08-0 plus a few unrelated patches.
Relevant kernel config options:

CONFIG_SND=m
CONFIG_SND_TIMER=m
CONFIG_SND_PCM=m
CONFIG_SND_JACK=y
CONFIG_SND_VERBOSE_PROCFS=y
CONFIG_SND_VERBOSE_PRINTK=y
CONFIG_SND_SOC=m
CONFIG_SND_OMAP_SOC=m
CONFIG_SND_OMAP_SOC_MCBSP=m
CONFIG_SND_OMAP_SOC_OMAP3_BEAGLE=m
CONFIG_SND_SOC_I2C_AND_SPI=m
CONFIG_SND_SOC_TWL4030=m

I had to manually modprobe snd-soc-omap, snd-soc-omap3beagle, and snd-soc-omap-mcbsp.
With these modules loaded, everything works normally.

Something probably needs to change so these modules get loaded automatically.
Is that what this bug is really about?

We want sound to work out of the box. No fiddling.

So whatever we need to change to at least get speaker-test doing what it should is a good first step.

Andy, did you perhaps miss a module when trying the manual modprobing?

Two of the modules seem to be simply missing a MODULE_ALIAS() for auto-loading to work. The third, snd-soc-omap3beagle, I'm not sure how to handle, investigating.

Kiko is right. I must have missed something. I just tried what Mans mentioned (changed beagle to overo equivalent) and everything worked again.

Pending an upstream approved fix I am adding this patch to the packaged kernel:

You need to add http://lists.linaro.org/pipermail/linaro-dev/2011-September/007331.html as well.
