hi guys i have an ecs ez tv tuner... picture is coming in great, but the sound it produces is horrible... the card is a pci card...it has an audio out , you have to connect a wire that came with it from the audio out into the mobos audio in....and i have verified that the static noise is being produced when that wire is plugged. i have isolated the wire so it wont go through the power llines but the static is still there:(

For systems that show good video but noisy analog audio from an ECS EZ TV tuner (the situation reported by and ), the most effective approach is a short, methodical isolation sequence. The checklist below expands on 's suggestions with concrete tests and likely fixes so the true source—card, cable, motherboard input, software, or grounding/EMI—can be identified quickly.

  1. Test the input: connect a known-good line-level source (phone or CD player) to the exact same motherboard line-in. If the noise remains, the mobo/input or the wiring is at fault; if it disappears, the tuner or its lead is the prime suspect.
  2. Bypass the mobo: connect the tuner's audio-out to active speakers or headphones (proper adapter). Persistent static there points to the tuner or its shielding.
  3. Swap to a short, shielded RCA/3.5mm cable and route it away from PSU, GPU, and power cables; fit a ferrite bead if available. Cheap jumpers and long runs commonly introduce hiss.
  4. Prefer the rear panel line-in over front-panel or internal jumpers—front wiring is often noisy. Also ensure the PCI card bracket is screwed down firmly for best chassis grounding.
  5. Software/driver checks: disable AGC/microphone boost or extra processing in the TV app and Windows mixer, set input sample rate to a standard (e.g., 44100 Hz/16-bit), and confirm the tuner is routed to the correct playback device.
  6. Ground/hum check: try a different mains outlet or an inexpensive RCA ground-loop isolator. Low-frequency hum (50/60 Hz) usually means a grounding issue; high-pitched hiss suggests shielding or gain problems.
  7. Hardware isolate: move the card to another PCI slot or another PC. If the card is noisy in any chassis, replacement is indicated.

Interpretation notes: hum = ground loop; hiss = shielding/amplifier noise; clicks = loose contact. Take standard ESD precautions when reseating hardware. If drivers, routing and the isolation steps above do not cure the problem, the most reliable remedies are a higher-quality shielded interconnect, a ground-loop isolator, or replacing the tuner with a different internal or external/USB unit.

a) Make sure you're connecting it to Line-in jack (not mic). Also make sure, if you are using internal connectors, that you're not connecting it to CD Audio in nor aux in.

b) Use retail cables. (not some lose wires)

c) If possible, redirect audio to on-board sound card via software or drivers.
