The dmesg results indicates which decimation values are used to downsample, yielding this table of twelve valid hardware rates:. In some cases cards have multiple signal sources a tuner and an external composite video and audio input pair, for example. For example, the box labeled model may contain one of these:. Never did get it to work in 10 so I put together a different PC with 7 and found some drivers, not from Leadtek, that work, but make the tuner appear to be for some other non-US region. My Computer Computer Type: The following cards are said not to work, but it’s not known if they are wired the wrong way, not properly initialized, or just mistakenly thought not to work:.

Sometimes you can play around with sample frequencies and input gain settings and improve things.

Intel Core i7 2. My Computer Computer Type: In these designs there will be an analogue switching IC between the two input sources and the BT87x.

That’s no problem because being NTSC it’s useless. New 23 Dec 2. The time now is On the datasheet, the relevant pins are 94, 98, and This page auio been accessed 29, times.

The wiring varies; the sound can come through on different bt8778 cf.

Btaudio (bt) – LinuxTVWiki

The digital mode requires an additional digital audio source, such as the MSP34xx, which not all cards have. The ADC audio stage runs a 1.

Analogue mono audio comes via the tuner or an external input source onto one or both of the BT87x analogue audio input pins. He notes that by editing the btaudio driver, it’s possible to make the ADC accept a decimation value lower than 4 for even higher sampling rates.

While a digital signal processor such as the MSP34xx is required for btaudio’s digital mode, any bt87x card has the required hardware to work with btaudio’s analog mode. Retrieved from ” https: Hauppauge model labels are often uninformative. Although all cards with BT87x chips are capable of supporting btaudio, not all cards do. Petr Vandrovec describes a case where a bt card fails to work with the btaudio driver unless it is first initialized by a Win98 driver:.
