Stacked with 48000Hz

Post by korakios »

Hi,
I try to use my onboard audio which has 1 mic and 1 stereo out.
The mic is always on 48000Hz sample rate. On windows I can use Asio4All and 44100Hz by simply disabling the mic as input.
I tried jack as playback only device but still jack sees that input is 48000Hz and ignores 44100
Is there any way to run at 44100Hz ?

Hi korakios!

You should be able to use zita-resampler, I don't use for my microphone but I use it to play a 44100hz Ardour session through a Bluetooth adaptor that is locked at the bluetooth standard of 48000hz. I'm on a different machine right now but I'll see if I can find the commandline for an example..

Here is some info: http://kokkinizita.linuxaudio.org/linux ... mpler.html

Hi Gmaq, it's been a while, hope everything is ok!
I think the problem is with jack server
starting jack as duplex I get a warning

Code: Select all

playback and capture sample rates do not match (48000 vs. 44100)
When I start jack as playback only device (I don't want to use the mic) no error is displayed , even in command line everything looks normal ,
but still jack displays 48000Hz instead of 44100Hz

Edit , it seems to be hardware related and ALSA issue of ALC3271 chip ,still jack should give a warn that the requested sample rate is not available and exit
