Hello!
I'm struggling with playback sample rate from echo indigo IO card. If i
try to just send wav file sampled at 44.1KHz to hardware destination like:
aplay -D hw:1,0 badboys.wav
Playing WAVE 'badboys.wav' : Signed 16 bit Little Endian, Rate 44100 Hz,
Stereo
it plays roughly two times slower then it should.
If i configure the hardware rate to be 48KHz like this
pcm.indigo {
type hw
card 1
rate 48000
}
and send the same file to it like:
aplay -D "indigo" badboys.wav
Playing WAVE 'badboys.wav' : Signed 16 bit Little Endian, Rate 44100 Hz,
Stereo
Warning: rate is not accurate (requested = 44100Hz, got = 48000Hz)
please, try the plug plugin (-Dplug:indigo)
it plays nicely, just with the correct sample rate.
If i then do as was asked and send to hardware alias with fixed rate via
plug, like:
aplay -D "plug:indigo" badboys.wav Playing WAVE 'badboys.wav' : Signed
16 bit Little Endian, Rate 44100 Hz, Stereo
it plays a little slower than it should. If i check the ratio of time
the song is played to that it should i get the same ratio as of 48/44.1
I checked with onboard audio card (Intel 82801G ICH7) and with Terratec
Aureon USB: both play back with correct rates out of the box.
I'm running Ubuntu 6.10, kernel 2.6.17-10, alsa 1.0.12rc1 (it's 1.0.11-5
in terms of ubuntu), alsa-firmware 1.0.11
Could please somebody help me or give directions for further search?
