Fresh install ubuntu 25.04 on the laptop. Running test case A2DP/SRC/SGSIT/ATTR/BV-04-C and AVDTP/SRC/ACP/TRA/BTR/BI-01-C will get FAIL result. Test case AVDTP/SRC/INT/SIG/SMG/BV-15-C will PASS at first time, if run the test multiple time will get INDCSV result.
Upgrade bluez package to 5.79-2ubuntu1.3 and all test cases can get pass result.

NOTE: Before running test case AVDTP/SRC/INT/SIG/SMG/BV-15-C, it require
to remove the PTS device from system.

     won't get fail result.
    - A2DP/SRC/SGSIT/ATTR/BV-04-C
     - check Advanced Audio Distribution profile (A2DP) version
    - AVDTP/SRC/INT/SIG/SMG/BV-15-C
     - Verify that the IUT (Implementation under test) is able to establish a stream connection to a previously configured remote SEP by establishing one L2CAP channel
    - AVDTP/SRC/ACP/TRA/BTR/BI-01-C
     - Verify that the IUT is able to issue a Set Configuration Reject response to the Initiator if the format of the media transport is incorrect

      - cleanup-endpoints-when-devices-been-removed.patch fix AVDTP/SRC/INT/SIG/SMG/BV-15-C, this test case will verify if the IUT follow the correctly command sequences (AVDT_Sig_Event_Registration-> AVDT_Get_Capabilities_Req-> AVDTP_GET_CAPABILITIES_CMD). If there is cached capability data, bluez won't send AVDT_Get_Capabilities_Req, PTS will treat it as fail. This patch make bluez clean cache when removing the device and able to get pass result with PTS.
