Is my condition of passing wind and excessive yawning upon hearing the call to prayer, despite my commitment to prayers, reading the Quran, and [reciting] remembrances, considered to be intrusive thoughts (waswasah)?

It is not far-fetched that what you are experiencing is a kind of demonic touch and possession, for excessive flatulence upon hearing the Athan (call to prayer) is one of the characteristics of Satan, as mentioned in the prophetic hadith. Therefore, you should increase in remembrance of Allah (Dhikr), recite the Qur'an, strive in acts of worship, and use ruqyah (Islamic incantations), all while seeking refuge in Allah through supplication. However, if what you mentioned is an illusion or a whisper from Satan (waswasah), you should not pay attention to it, and you must strive in worshipping your Lord without caring about it, lest it open a door to great evil and lead to obsessive whispers.
