AMD SB700 ALC888 ossrecord not working

Postby tearring » Thu Mar 22, 2018 3:52 pm

I have an board, the chip is AMD SB700 with the ALC888 codec

Firstly, under linux with alsa driver, the command "arecord -f cd x.wav" can work.
I can record by mic which inserted into the green jack on the audio connector.

Now, i replaced the alsa with oss, then ossplay, osstest can play well.
But command "ossrecord -l -t 20 /home.x.wav" cannot work at all.

I test all the jacks (pink, blue, green) on the audio connectors,
But the VU level hold on this status VU -------++ forever, which doesn't change anymore.

I think if the mic work ,the VU level should change from 0 to -------++

Here's the ossmix -v2 info

Please help me how to configure the mixer??

vmix0-channels <Stereo|Multich> (currently Stereo)
vmix0-src <High|OFF> (currently Fast)
Sample rate conversion quality used by the virtual mixer.

Virtual mixer uses internally a fixed sampling rate that can be set
using the 'vmixctl rate' command (usually 48 kHz by default). Applications
that want to use different rates will be handled by performing automatic
sample rate conversions (SRC) in software. This operation will consume
some additional CPU time depending on the quality. The following
alternatives are availabe:

Fast: Use fast linear interpolation algorithm (low quality).
Low: Use slightly better linear interpolation
Medium: Use an algorithm that provides good quality with moderate CPU load.
High/High+/Production: Higher quality algorithms that consume more CPU resources.
OFF: No sample rate conversions. Sample rate locked to the master rate.

'Fast' will work best in most cases. Only users with high end audio
cards and speakers should use the other settings.

As your microphone works with Alsa when plugged into the green jack I would suggest changing the green jack mode from front to input using:
ossmix input
You may also find that ossxmix is easier to use when experimenting with the various mixer controls.

Actually, my CPU arch is MIPS
I did not succeed in compiling OSS V4.2 on Linux system of MIPS arch, the following link is what i asked before:

At the moment, i ported it to VxWorks RTOS
I can make clear the following things:
1. The Audio Connector of Blue on my board is actually correspond to
2. ossmix front , that i can hear the audio from headphone which plugged into the blue jack

So, it should be the green on the audio connector is correspond to mixer ctrl.
But the default mode of is just input mode!!!
And when i execute ossrecord, i can't record any sound. The VU meter level is hold on "--------+" status.

By the way ,i enabled virtual mixer

Who can help me , I cannot use ossxmix to help adjusting every mixer value -_- T_T

And is there any oss mixer base on Qt gui ???
