The action on the pitch hasn't been very engaging but at least the Aviva Stadium music has united supporters from both teams - but not in a good way.
The stellar atmosphere created by cheering Ireland and Wales fans has been joined by a trumpet trumpeting at regular intervals, which hasn't gone down well with those in the ground, or with the supporters watching at home.
Ireland international Paul McShane was one of many who has voiced their displeasure on social media, with most people left annoyed and confused by the unusually loud instrument in attendance.
Here is how some people are responding to Trumpetgate, Ireland's newest sporting scandal.
Wouldn't be surprised if the trumpet player is being strangled by his own trumpet at half time.— Paul McShane (@pmacca15) March 24, 2017
If any Ireland fans want to get protest flags past security in the future, just wrap them up and put them inside a trumpet. Will be grand— Daniel McDonnell (@McDonnellDan) March 24, 2017
€100 for the person who finds the clown with the trumpet and shoves it up his hole #IRLWAL— Ross Zambra (@TheKingOfPing) March 24, 2017
Whoever brought that trumpet should be banned from all major sporting events in this country for life! #IRLWAL— Colm Cuddihy (@ColmCuddihy) March 24, 2017
