Windows 7 cannot auto-detect audio I/O
My HP e9280t has a built-in Realtek sound chip with multiple i/o ports. The digital port is a toslink. The analog ports are mini-ports.
The problem is that Windows 7 Ultimate x64 won't auto-select which audio port to use. Realtek tech support told me that Windows specifications allow their driver to output to audio xor digital audio ports. The hardware can do it, but Microsoft won't allow it. Microsoft sounds, TV stations with analog audio tracks, and optical disks with analog audio tracks will play only through the audio output. TV stations with digital audio tracks and DVDs with digital audio tracks can output to the digital toslink port to my Dolby 5.1 receiver/amplifier with up to 5 discrete audio channels. The big problem is that you must manually configure either analog or digiral audio outpout in Windows 7 to match the audio or digital sound track of the source media each time you switch from one to another.
I use media center with a hauppauge 2550 dual tuner. If I watch channel 7 (local ABC analog feed) and switch to channel 7.1 (local ABC digital feed), I must manually reconfigure the Windows sound system to output to the appropriate audio output. At the same time I lose all other windows sounds which will only work through the analog outputs. If I tune back to channel 7, I must again reconfigure windows sound system back to analog. True, I could leave Windows configured for analog audio and not hear the discrete 5.1 audio channels.
The rub is that it's no longer a stereo world. 5.1 and 7.1 is the norm. My old receiver/amplifier doesn't have 7.1, but it can detect whether it is to output mono, stereo, matrixed dolby surround, or digital dolby 5.1. Why can't Windows 7? Why would Microsoft dictate to Realtek that it cannot autodetect and switch outputs, or just output to all outputs so that the external receiver/amplifier select the desired sound source?
I expect a new Microsoft Media Center machine with Windows 7 Ultimate should be able to auto-select audio outputs.
Recommendations are desired.
