I have noticed that my drivers (c-media 18.104.22.1689) don't support simultaneous digital in and out.
Is it possible record an AC3 stream via S/PDIF-in and decode it ?
And.. does the clock of the input need to be synced with the clock of the output in this mode? Or does the chip have an asynchronous PLL for receive clocking?
OK, they installed fine, and work! A few issues, though: at first no digital out, only digital in worked.
then I was playing an MP3 and changed the 's/pdif 5V signal level' switch (what does that do anyway?) and winamp crashed, and the digital output was brought to life (toslink glowing red).
However, since then there is no way to revive the digital input without a reboot. no amount of switching and fiddling worked.
Also, what is the DAC level slider adjusting, exactly? it doesn't change the wav output volume, but that must go through the DAC, right?
QuoteAnd.. does the clock of the input need to be synced with the clock of the output in this mode? Or does the chip have an asynchronous PLL for receive clocking?Asynchronous PLL is a few cents more expensive than a synchronous PLL for both SPDIF-in and -out => c-media made the obvious choice.
Digital-in meaning direct loop-through to SPDIF-out ?
Quotethen I was playing an MP3 and changed the 's/pdif 5V signal level' switch (what does that do anyway?) and winamp crashed, and the digital output was brought to life (toslink glowing red).The 'official' cmedia driver might have set some registers which need to be unset for my way of handling things.
QuoteAlso, what is the DAC level slider adjusting, exactly? it doesn't change the wav output volume, but that must go through the DAC, right?It's supposed to do that. It's setting soundblaster register 0x04 which has been marked in the cmedia specs as "Wave Volume".There's "Wave Volume" slider in the mixer, but that's just adjusting the volume software-wise in the kmixer.OK, thanks for the reports, I'm currently working on the next version.
René, thanks for the bug report. Power management is one of the few things which haven't been implemented yet - but it's pretty high on my list.
Thanks. I'll try it.. and ac3filter must be set to use direct sound or waveout ?
If I get a cheap audio card with an 8738, will I be able to do simultaneous digital and analog (stereo) out?
Is that a function of the audio chip, the soundcard, or the drivers?
And if so, can you recommend a cheap, reliable card that definitely does this?
I just noticed that mixer.exe still runs in the background, and it must have a memory leak or something since I've seen it grow to use over 100 megs of memory. Your drivers don't need mixer.exe, right? It's just left over from my old C-Media installation?
So is there anything I can tweak or do to enable 44.1 kHz output?Thanks in advance for any hints!
I'm using it successfully with a Nightingale card and Vista.
What does "The current release might be a bit unstable." mean,is it the 0.95, that is unstable or the 0.96?
There are two ways:1. Use non-WaveRT drivers and a kernel streaming outplug plugin. (foo_out_ks.dll for foobar, out_ks for winamp).2. Use WaveRT drivers and an output plugin which employs "exclusive access" to the soundcard. The exclusive access mode of the vista sound system bypasses all the mixing by design and passes the stream directly onto the soundcard. If I recall correctly, this is just an extra flag for opening a sound device through WaveOut, so the implementation should be fairly easy, but I haven't seen any support for that in output plugins. But I guess it's just a matter of weeks before this gets implemented.
Method one would mean not to take your drivers, since they are (now) WaveRT, is that right?
And method 2..."it's just a matter of weeks before this gets implemented" - do you mean by you?
