am 8d2d4932: audioflinger: fix duplicating track sampling rate

        // since client and server are in the same process,

        // the buffer has the same virtual address on both sides

        mClientProxy = new AudioTrackClientProxy(mCblk, mBuffer, mFrameCount, mFrameSize);

        mClientProxy->setVolumeLR((uint32_t(uint16_t(0x1000)) << 16) | uint16_t(0x1000));

        mClientProxy->setSendLevel(0.0);

        mClientProxy->setSampleRate(sampleRate);

    } else {

        ALOGW("Error creating output track on thread %p", playbackThread);

    }
