Audio capture on the 293e (82801IBM)   
Hello,

I am having issues capturing audio on the said chip. waverec shows it is recording audio but there is nothing on the 
playback of the recorded file.

I used io-audio -d intel_hda on 6.5

I'm not sure that any audio driver developers are monitoring this forum. 
  I would suggest contacting QNX support for assistance with this.

Hi, 

Can you playback other audio?

Thanks and best regards,

Johnny

Also, Input Gain on the Audio Mixer doesn't show anything. (refer to attached screenshot)

@Johnny,
Yes, audio playback is working normally.

Can you try the attached DLL deva-mixer-hda.so? Just find this file in your system, make sure keep a copy for the old 
deva-mixer-hda.so, replace the old one in your system, and restart the system.

Best regards,

Johnny

Hi Johnny,

I tried the new mixer DLL, I can see that there is already an Input Gain control on the mixer program but I still am not
 able to capture audio. There is nothing on the sloginfo too.

The mic I am using works on my laptop under Windows XP. I am also looking into whether the connectors I am using the mic
 on are also at fault.

Thanks for that file, how did you obtain it?

Can you plug the output of a CD player to your MIC IN and maximise its output and see if you can capture its audio?

I did not maximize anything but I was able to capture audio via MIC IN using 3.5mm-to-3.5mm against an iPhone playing an
 mp3.

I attached the slog output, the bigger file is when I captured and played back successfully both via LINE IN and MIC IN 
through the iPhone. The smaller one is capture and playback using just the a regular microphone. I have not used any 
other microphone unit yet but this one works in a laptop running Windows.

By the way, this is what it looks like after I tried using your new DLL.

Re: Audio capture on the 293e (82801IBM)   
That looks good. Can you do the following:

1. slay io-audio
2. start the io-audio as: "io-audio -d intel_hda -l 0x7ffffff -vvv"
3. run: "sloginfo -c > /tmp/hda.log"
4. post the hda.log 

BTW, have you tried to input an audio from a CD/IPOD/MP3 or even your
laptop's headphone output and see if your MIC IN can capture?

RE: Audio capture on the 293e (82801IBM)   
Sorry it's my mistake. Should start the driver as:


io-audio -l 0x7fffffff -d intel_hda

Note the "-l" is the lower case of "L".

Here is the result of the corrected io-audio parameter sequencing.

Can you try this one and see if you can capture via microphone?

Used microphone via MIC IN with the new dll, still nothing.

I attached the startup, record and playback slog outputs for your reference.

The same with the previous DLL you gave me, the Audio Mixer photon app shows only Input Gain having slider controls 
under Record Settings. I took a screenshot of this one too and it's also in the attached zip file.

A little update. I didn't execute anything since but I just did an sloginfo a few minutes after and I got some more.
