Hi,
Im using OMAP4460. Amixer settings for the ALSA soundcard driver in order to enable audio output are shown below.
# amixer sset Headset 10
Simple mixer control 'Headset',0
Capabilities: pvolume penum
Playback channels: Front Left - Front Right
Limits: Playback 0 - 15
Mono:
Front Left: Playback 10 [67%] [-10.00dB]
Front Right: Playback 10 [67%] [-10.00dB]
# amixer sset 'Headset Right Playback' 'HS DAC'
Simple mixer control 'Headset Right Playback',0
Capabilities: enum
Items: 'Off' 'HS DAC' 'Line-In amp'
Item0: 'HS DAC'
# amixer sset 'Headset Left Playback' 'HS DAC'
Simple mixer control 'Headset Left Playback',0
Capabilities: enum
Items: 'Off' 'HS DAC' 'Line-In amp'
Item0: 'HS DAC'

This used to work earlier. But now, I'm just able to hear noise and no audio from the track that is playing.
What I now did is, I tried with some other soundcard and digital audio device combination. In my case, plughw:0,4 . The pipeline fails and returns error.
But now, if I try the previous soundcard and digital audio device combination, i.e. plughw:0,8, audio works perfectly fine. I'm able to hear the song and there's absolutely no noise.

I'm not able to figure out what exactly is wrong. Please help.
Thanks in advance,
