In this case, and in this case only, you will not get the broadcast audio. The bt and bt the latter no longer in production include a high-frequency Analog to Digital Converter, supporting both 8 and 16 bits audio at samples per second. According to the datasheet, sections 2. Some cards are reported to work, but the quality is poor; there may be individual differences within a model series. Why this old card?

If your tv audio works more or less on boot, please add a page about it and any kernel options required to get it going to the wiki. According to the datasheet, sections 2. As of kernel 2. Although all cards with BT87x chips are capable of supporting btaudio, not all cards do. Nothing short of a soldering iron will help you. This is useful if you would like to reserve your sound card for other functions, if you want to have multiple tuner cards in one computer, or if your sound card does not handle full-duplex.

For example, the box labeled model may contain one of these:.

DriverMax – MEDIA – Conexant – Conexant BT Audio Capture Computer Driver Updates

Those are generally controlled control meaning mode and input selection via i2c using the tvaudio driver. See the captured graph after power-on and compare with the graph captured after booting Win The digital mode requires an additional digital audio source, such as the MSP34xx, which not all cards have. The analog mode of the btaudio driver should just work on any BT87x card. There are already Aver card-specific audio initialisation functions in the bttv driver to handle this case — Petr himself wrote them.


Error 10, Windows doesn’t know what’s wrong, or if it does know, it’s not telling.

This page has been accessed 29, times. Audko page was last modified on 25 Januaryat 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. Got a link to the actual driver download, instead of Driver Dr?

Sometimes you can play around with sample frequencies and input gain settings and improve things. I have seen at least one card where the switcher IC routes both audio and video, and with the audio output from the switch only going to the external audio out, so you can use bf878 for the TV tuner, but not for the external audio input.

Because Leadtech told the video industry to go micturate up a rope, it ignores all analog copy protection systems.

MEDIA – Conexant – Conexant BT878 Audio Capture Computer Driver Updates

Run it in compatibility mode for Vista. In some cases cards have multiple signal sources a tuner and an external composite video and audio input pair, for example. Digital audio won’t work in the majority of cases because there is no external digital audio audoo to drive it. The bt and bt the latter no longer in production include a high-frequency Analog to Digital Converter, supporting both 8 and 16 bits audio at samples per second. Why this old card? Rather annoying when capture software falsely claims old home videos are “copy protected”.


Windows 10: bt878 video capture in Win 10 x64?

New 23 Dec 3. Btaudio is, in theory, fully replaced and conflicts with Snd-bt87x alsa bt driver.

On the datasheet, the relevant pins are 94, 98, and I tried Driver Dr. Has anyone been able to get any bt based video capture cards working in Windows 10 x64? In some cases, the manufacturer elected not to connect the TV tuner analogue bt788 out to one of the two ADC analogue inputs, which means you’ll get no sound from btaudio.

Vertical lines denote The analog device created by the btaudio driver has three mixer channels, called Line1, Line2, and Line3. New 23 Dec 2.
