Hi Developers,

I need to configure my audio device such as to use only LEFT or RIGHT Channel. I have carried out following steps to proceed with

1) Opened PCM playback Device 2) Configured its hardware and Software parameters 3) Open mixer 4) Attached Mixer to playback device 5) Registered Mixer 6) Loaded the mixer 7) Get the first element of mixer

A) Now when i use following API, snd_mixer_selem_is_playback_mono(aElem); i found mixer is using MONO channel. But i am configuring my PCM Device for 2 channels

I am using snd_mixer_selem_set_playback_switch() API to set right or Left channel to MUTE {Does not work}

If i set all channels to Mute {Works fine} snd_mixer_selem_set_playback_switch_all (aElem, 0)

Also i am able to set SND_MIXER_SCHN_MONO to mute {works fine} snd_mixer_selem_set_playback_switch(aElem, SND_MIXER_SCHN_MONO, 0)

B) There is also an API in my MIXER driver to set the right and left balance, but i did not find any API in Application to do so {Is there any such API in Application}.

Thanks in Advance,
