Hi,

  Use the following amixer commands before issuing a playback

amixer cset name="DL1 Media Playback Volume" 120

amixer cset name="SDT DL Volume" 120

amixer cset name="DL1 MM_EXT Switch" 1 

amixer cset name="Sidetone Mixer Playback" 1 

amixer cset name="DL1 Mixer Multimedia" 1

Mukund

Hi,

  Looks like you are using an old version of the codec driver.

You can request for the latest TLV320AIC3100 driver corresponding to kernel 3.0 at

http://www.ti.com/tool/codecdrivers-sw

Regards,

Mukund

Hi, we're also looking for the driver but there are no TLV320AIC3100 drivers for OMAP4xxx or 3.x kernels withing the Audio Codec Selection Tool (http://www.ti.com/tool/codecdrivers-sw) and codecdrivers-sw@list.ti.com is not replying.

I get drivers.

But I have a problem. There is no fm/fm34.h in package.

This files included in sound/soc/omap/omap4_panda_aic31xx.c. 

Hi,

  You can safely remove the include file. If there are any dependencies those can also be removed.

Regards,

Mukund

Can anybody say, how to debug this problem?

Hi,

 Sounds like the ABE back-end and front-end are not mapped. The following commands maps the Media LP to MM_EXT resulting in data flow inside ABE.

  Use the following amixer commands before issuing a playback

amixer cset name="DL1 Media Playback Volume" 120

amixer cset name="SDT DL Volume" 120

amixer cset name="DL1 MM_EXT Switch" 1 

amixer cset name="Sidetone Mixer Playback" 1 

amixer cset name="DL1 Mixer Multimedia" 1 

Regards,

Mukund

Thank you Mukund, but where to get amixer for ICS?

I also see many error on the logcat

I/TabletStatusBar( 234): DISABLE_EXPAND: yes

I have such output for aplay -L

Is it correct? I also have

<3> tlv320aic3110 Media1 LP: no BE found for PDM_DL2
<4> tlv320aic3110 Media1 LP: asoc: tlv320aic3110 Media1 LP no valid playback route from source to sink
<3> tlv320aic3110 Media1 LP: dsp: no backend DAIs enabled for tlv320aic3110 Media1 LP

and no sound. 

Now I have sound only when I run such commands

1. Start Music player from ICS.

2.No sound

3. Run

4. Now I have sound on ICS

5. When I close Music player, and run it again I have no sound.

Any idea / help? 

What is a reason of such error

tlv320aic3110 Media1 LP: no BE found for PDM_DL2 ?
