[SOLVED] ASUS Xonar STX Questions (ossmix Options)...

Postby adamlau » Thu Oct 20, 2011 8:23 am

What does the 'ext.monitor.analog' option do? Sound plays through the analog line outs regardless of ON, or OFF.

Code: Select all
$ ossmix
Selected mixer 0/CMedia CMI8788
Known controls are:
ext.monitor.analog ON|OFF (currently ON)


Does the 'spdif-out.adc/dac' option affect the analog path in any way (I presume not)?

Code: Select all
spdif-out.adc/dac ON|OFF (currently ON)


What is the difference between 'Consumer' and 'Professional'?

Code: Select all
spdif-out.pro <Consumer|Professional> (currently Professional)


What does 'spdif-out.copy' refer to? Copy what?

Code: Select all
spdif-out.copy ON|OFF (currently OFF)


What does 'spdif-out.pre-emph' refer to? Pre-emphasize what?

Code: Select all
spdif-out.pre-emph ON|OFF (currently OFF)


What does 'spdif-out.vbit' refer to? Virtual bitrate?

Code: Select all
spdif-out.vbit ON|OFF (currently OFF)


OSS 4.x User's Guide (oss_cmi878x) indicates the presence of an 'oss_cmi878x.conf' which does not reside in '/usr/lib/oss/conf'. Does anyone else have this file present?

What does the 'ext.monitor.analog' option do?
Mix the analog input into the analog output.

Does the 'spdif-out.adc/dac' option affect the analog path in any way (I presume not)?
It selects what is played on the S/PDIF output.

What is the difference between 'Consumer' and 'Professional'?
None at all because the hardware does not have this switch. (Apparently, the driver writer incautiosly believed the datasheet. :wink:)

What does 'spdif-out.copy' refer to? Copy what?
"Copyright asserted". If set, the device that receives the S/PDIF data should not allow to record it.

What does 'spdif-out.pre-emph' refer to? Pre-emphasize what?
It labels the data as being recorded with pre-emphasis; the device that receives the S/PDIF data should deemphasize it.

What does 'spdif-out.vbit' refer to? Virtual bitrate?
Validity bit. If off, the data is labeled as being valid PCM data; if set, the data is labeled as being valid data of another type such as Dolby or DTS.
