 Posted: Wed Jul 11, 2012 10:57 pm Post subject: [SOLVED] ogg123 and libao sample rate error |
 |
|
So, I recently recompiled my system with emerge -e world. I ran into some problems with gconf (Bugs #408857 and #411237) which I managed to fix by upgrading gconf to version 3.2.5. I just discovered recently that I also have issues with ogg123. I'm not sure if this is also due to recompiling. Anyways, when trying to play a vorbis file, ogg123 gives the error ao_alsa WARNING: sample rate 44100 not supported by the hardware, using 48000. Then it continues to play the file without resampling, giving my vorbis files a higher pitch than they should have. mpg123 is able to play at 44100, but seems to use ALSA directly instead of libao. I don't know of any other software that uses libao to test with.
I did discover that if I begin playing an mp3 with mpg123, then begin playing a vorbis file with ogg123 at the same time, ogg123 gives the error ao_alsa WARNING: Unable to open surround playback. Trying default device... then begins playing the vorbis file at the normal rate. I can then stop mpg123 and listen to the vorbis track just fine.

I found that ogg123 is trying to use the device 'front' instead of 'default' when it's linked against libao-1.1.0.
I tried adding the following to asound.conf:
| Code: | pcm.!default {
type hw
card 0
device 1
} |
This gets ogg123 playing at the correct sample rate, but then mpg123 begins failing with the following error:
| Code: | [sdl.c:78] error: Couldn't open SDL audio: No available audio device
[audio.c:630] error: failed to open audio device
[mpg123.c:542] error: failed to reset audio device: No such file or directory |
Downgrading to libao-1.0.0 allows both programs to work without any configuration changes to ALSA. This bug at the xiph tracker seems awfully similar. I'm wondering if I should open a new report or follow up with that one. Maybe someone could suggest other things I could try? I'm not all that familiar with ALSA configuration. |

Hello,
you can choose the libao default driver by writing this line
| Code: | | default_driver=alsa |
to ~/.libao and/or /etc/libao.conf. Then, ogg123 should follow the configuration of Alsa in ~/.asoundrc and /etc/asound.conf or the default one if none exist.

| Alright, adding default_driver=alsa to libao.conf wasn't enough as libao was already using ALSA by default. Adding dev=default worked though. Thanks! |
