DSD Windows XP - no audio

[ozdsd]

My setup:

- Windows XP with Realtek HD Audio
- SDR#
- DSD 1.7 (cmd line: dsd -i /dev/dsp -o /dev/dsp -fa)
- VB-CABLE Driver
- Sounds and Audio Devices \ Audio \ Sound playback\ Default device: Realtek HD Audio output
- Sounds and Audio Devices \ Audio \ Sound recording\ VB-Audio Point


What works:

DSD shows rolling messages like these:

Sync: -P25p1 mod: GFSK inlvl: 83% nac: 1D3 src: 0 tg: 0 TSDU
Sync: -P25p1 mod: GFSK inlvl: 83% nac: 1D3 src: 0 tg: 0 TSDU
Sync: -P25p1 mod: GFSK inlvl: 83% nac: 1D3 src: 0 tg: 0 TDU
Sync: -P25p1 mod: GFSK inlvl: 84% nac: 1C7 src: 0 tg: 0 TSDU
Sync: -P25p1 mod: GFSK inlvl: 83% nac: 1D3 src: 0 tg: 0 TDU

Sync: -P25p1 mod: GFSK inlvl: 83% nac: 1D3 src: 0 tg: 0 TSDU

What does not work? There is NO audio.

Any idea? Please help.

I found out that a continuous stream of TSDU is an indication of the control channel signal.

How do I find the voice channel?

I found the voice channel next to the control one. It is rarely used so I missed it.

The issue is resolved. All works now.
