Hi all, Several of you have emailed recently about No Audio from the Tuner on Bt878 Hauppauge cards (usually with the NICAM stereo chip) Andrew Gordon has saved the day. He has used a ossilicope and multi-meter to work out the hardware layout of the new Hauppauge boards. It seems that the Tuner Audio no longer has a direct route to the Audio Mux. It only goes into the 34xx NICAM STEREO chip. From there it goes into the Audio Mux. So, we need to initialise the 34xx STEREO chip before we can get any audio on Hauppauge BT878 cards. Note: The external audio input should still work. Only Tuner Audio is affected. Note2: Old hauppauge cards has a direct link from the Tuner's mono audio out to the Audio Mux and also a link from the Stereo Chip to the Audio Mux.
