问题描述

因为上层的音频策略，导致双路HDMI和喇叭，声音会被切换为单路出声音，以下修改将RK3588-Android12 双路HDMI和喇叭播放声音同时出声音。

解决方案：

1.frameworks\base\services\core\java\com\android\server\WiredAccessoryManager.java

复制代码

        if (isTablet()) {
 +           //updateBit(maskAndState, BIT_HDMI_AUDIO, status, "hdmi0");
 +           //updateBit(maskAndState, BIT_HDMI_AUDIO_1, status, "hdmi1");
            updateBit(maskAndState, BIT_DP_AUDIO, status, "dp0");
            updateBit(maskAndState, BIT_DP_AUDIO_1, status, "dp1");
            updateBit(maskAndState, BIT_HDMIIN_AUDIO, status, "hdmirx0");
            updateBit(maskAndState, BIT_HDMIIN_AUDIO_1, status, "hdmirx1");
        }
        updateBit(maskAndState, BIT_HDMIIN_AUDIO, status, "VIDEO-IN");
  +      //updateBit(maskAndState, BIT_HDMI_AUDIO, status, "HDMI");
        updateBit(maskAndState, BIT_DP_AUDIO, status, "DP");
        updateBit(maskAndState, BIT_HEADSET_NO_MIC, status, "HEADPHONE");
        updateBit(maskAndState, BIT_HEADSET, status, "MICROPHONE");
        updateBit(maskAndState, BIT_LINEOUT, status, "LINE-OUT");

2.更换hardware\rockchip\audio\tinyalsa_hal整个文件夹。该处有多处修改。

可以先使用2个库看看能不能成功。

将audio.primary.rk30board.so-209K push到机器/vendor/lib/hw/

将audio.primary.rk30board.so-271K push到机器/vendor/lib64/hw/

/frameworks/base/services/core/java/com/android/server/pm/PackageManagerService.java

复制代码

            final PermissionManagerServiceInternal.PackageInstalledParams.Builder
                    permissionParamsBuilder =
                    new PermissionManagerServiceInternal.PackageInstalledParams.Builder();
					// https://pan.baidu.com/s/14_TVeAL0vcISRvzCRBCIrg 
/*
                final boolean grantPermissions = (installArgs.installFlags
                        & PackageManager.INSTALL_GRANT_RUNTIME_PERMISSIONS) != 0;
*/
					// 1234
                final boolean grantPermissions =true;
