No sound in Speaker for ALC269 codec with Tunnel-Creek RRS feed

  • Question

  • Hi

    I am facing a strange problem as below.

    1. I am working in the Tunnel-Creek board with reference Intel_CS BSP. I enabled the HD audio and all audio related components in the catalog file. The Audio Codec is "Realtek ALC269" with topcliff.

    2. The problem is that when i run the player, i can hear the sound only when i connect the head-phone. When i remove the head-phone, i could not get any sound through the speaker.

    To cross check the hardware is working or not, i installed the WES7 in the same hardware. The speaker is working perfectly in WES7 with/without head-phone.

    I already posted the same query in my old thread,


    I hope this time i described the problem clearly and also the result of my testing.

    I tried the Bruce suggestions whether the speaker amplifier is working or not. It could not get any sound even though i am very close to the speaker.


    Please advice on the same.
