AverMedia TV98 (BT-878 chip) Driver
Sometimes problems show up with bttv just because of the high load on the PCI bus.
Both bttv and btaudio AverMedia TV98 (BT-878 chip) a insmod option to set the PCI latency of the device. Some mainboard have problems to deal correctly with multiple devices doing DMA at the same time. Updating the IDE driver to get the latest and greatest workarounds for hardware bugs might fix these problems. IRQ sharing is known to cause problems in some cases.

It works just fine in theory and many configurations. AverMedia TV98 (BT-878 chip) you have stability problems you can try if one of these options makes your box work solid. Thus the arbiter defaults to the video function at power-up and parks there during no requests for bus access.
This is desirable since the video will request the bus more often. However, the audio will have highest bus access priority. Thus the audio will have first access to the bus even when issuing a request after the video request but before the PCI external arbiter has granted access to the Bt Neither function can AverMedia TV98 (BT-878 chip) the other once on the bus.
Do not reassert REQ to request another bus transaction until after finish-ing the previous transaction. Since the individual bus masters do not have direct control of REQ, a simple logical-or of video and audio requests AverMedia TV98 (BT-878 chip) violate the rules. Thus, both the arbiter and the initiator contain FX compatibility mode logic.
However, once the GNT is issued, this arbiter AverMedia TV98 (BT-878 chip) lock in its decision and now route only the granted request to the REQ pin.
AverMedia TV98 (BT-878 chip) is the arbiters responsibility to allow AverMedia TV98 (BT-878 chip) request to flow through to REQ and not allow the other request to hold REQ asserted. The decision lock may be removed at the end of the transaction: The arbiter decision may then continue asynchronously until GNT is again asserted. Interfacing with Non-PCI 2. This is non PCI 2. This prevents a bus transaction from starting the same cycle as GNT is de-asserted.
This also has the side effect of not being able to take advantage of bus parking, thus lowering arbitration performance.
Making video work often is not a big deal, because this is handled completely by the bt8xx chip, which is AverMedia TV98 (BT-878 chip) on all boards. But sound is handled in slightly different ways on each board. To handle the grabber boards correctly, there is a array tvcards in bttv-cards. Sound will work only, if the correct entry is used for video it often makes no difference. The bttv driver prints a line to the kernel log, telling which card type is used.
BT Hauppauge AverMedia TV98 (BT-878 chip) [autodetected] You should verify this is correct. Some boards have an extra processor for sound to do stereo decoding and other nice features.
The msp34xx chips are used by Hauppauge for example. If your board has one, you might have to load a helper module like msp Start writing a new one.
Well, you might want to check the video4linux mailing list archive first Of course you need a correctly installed soundcard unless you have the speakers connected directly to the grabber board. ALSA for example has everything muted by default. Looks like some driver hacking is AverMedia TV98 (BT-878 chip).

Below is a do-it-yourself description for you. The bt8xx chips have 32 general purpose pins, and registers to control these pins. They can be used for input and output.
Most grabber board vendors use these pins to control an external chip which does the sound routing. But every board is a little different.
