Bug Description

Hi,

I have the gumistix overo tide with tobi board. It currently doesn't produce sound via the headset jack. I've reset alsamix to ensure it's ok, check the jack connection and so on to no avail. I see no errors in syslog to account for this. In fact everything says it should work.

Joey - I just tried this on my board and it worked correctly. What kernel version are you on? I'm on:

I tested the speaker on my workstation with the same command and it
works fine. I unplugged the speaker and put it into the mic jack just
to see if that would work on the tobi but no luck. I suppose it's
possible I have a bad tobi.

Hi,

I've tested this now with a different analog headset and also with a logitech USB headset (to demonstrate that it's not a failed tobi board). All instances it looks like sound is being played but nothing is heard. I've ensured alsamixer is set correctly.

I'm seeing this now as well. The original test I did was using the alpha 1 drop:
 linaro-natty-headless-tar-20101202-1.tar.gz

Maybe something has changed since then?

I've found a hack to get this working. The file:
 /var/lib/alsa/asound.state

has two important fields set to false:

  name 'HeadsetL Mixer Voice'
  name 'HeadsetR Mixer AudioR1'

when I manually edited the file and then ran "alsactl restore" I was able to get sound working.

I'm not sure why the default file is generated incorrectly and why I couldn't enable this using the alsamixer GUI

That patch worked for me too! I have sound for the first time.
