TFT_eSPI库与Audio库发生冲突，原因是TFT_eSPI库引用了FS.h，其中命名空间为fs,定义了FS类，Audio.h开启sdFat库后，也有一个fs命名空间，然后在sdFat类基础上又定义了一个FS类。

audio.h文件

#define SDFATFS_USED  // activate for SdFat
#ifdef SDFATFS_USED
//typedef File32 File;
typedef FsFile File;

namespace fs {
    class FS : public SdFat {
    public:
        bool begin(SdCsPin_t csPin = SS, uint32_t maxSck = SD_SCK_MHZ(25)) { return SdFat::begin(csPin, maxSck); }
        bool begin(SdSpiConfig config){return SdFat::begin(config);}
    };

    class SDFATFS : public fs::FS {
    public:
        // sdcard_type_t cardType();
        uint64_t cardSize() {
            return totalBytes();
        }
        uint64_t usedBytes() {
            // set SdFatConfig MAINTAIN_FREE_CLUSTER_COUNT non-zero. Then only the first call will take time.
            return (uint64_t)(clusterCount() - freeClusterCount()) * (uint64_t)bytesPerCluster();
        }
        uint64_t totalBytes() {
            return (uint64_
