Thanks for working on this
It seems to show something different though:
"
A bug was just triggered in audio_calloc
Save all your work and restart without audio
I am sorry
"
AUD_open_out() is called with audsettings: {freq = 1, nchannels = 2,
fmt = AUDIO_FORMAT_S16, endianness = 0}
And that's it. Any idea?
Hi,
the scary message is expected and doesn't mean this qos-test failed.
This is the currently not so silent 'the audio subsystem should (...)
silently give up' case.
Ok, but it's not silent. According to the AC97 spec, "if the value
written to the register is supported that value will be echoed back
when read, otherwise the closest (higher in case of a tie) sample rate
supported is returned". We should probably pick a low sample rate,
like 8000 (see Table 32 in spec 2.1) for anything below it.
Hi,
I don't think we should limit the lowest sample rate to 8000 Hz. The
sample rates in AC97 revision 2.1 Table 32 are sample rates the codec
should support at minimum. We are free to support the whole 1-65535 Hz
sample rate range.
FWIW, a minimum sample rate of 1 Hz also does not make much sense. You
cannot hear that frequency anymore... so it does not really make that
much sense to support such low frequencies here. Just my 0.02 €.
Still useful when using a sound card as signal generator, i.e.:
