Subject: Question about microphone usage on OMAP2430SDP

Message-ID: <dbf1574b0701231757o7186a24dk39d9483ae371eab5@mail.gmail.com> (raw)
hi,
I'm trying to record some voice through Main/Sub & Headset microphone on
OMAP2430SDP board. But only noises is recorded (does not sound like voice).
I have used
1. cat /dev/dsp > audio.out & cat audio.out > /dev/dsp --> failed
2. sample program from pjsip (open source sip protocol stack)
which config. sample rate=44100, ch=2, bits=16
(able to record sound in x86 system) --> failed
Besides main/sub mic, I noticed that the record source can be switch to
Headset by ioctl OSS driver. I tried to use audio connector to 3.5mm microphone
to the headset plug. But still doesn't work.
I'm using linux-2.6.14-omap2430 downloaded from TI webiste. Does anyone ever
successfully record anything from OMAP2430 main/sub or headset mic? And how
can i correctly connect microphone to on-board headset plug? I'm currently using
audio connector grab from nokia mobile accessory. Thx for answering my question.
Best Regards,
Robert
