概 要音程が1オクターブ上がっている。
詳 細As of version 0.184, arkanoid and all its clones, as well as arkatour, have all sounds and music pitched twice as high as they were in 0.183 and prior.

The lower pitch heard pre-0.184 matches with nearly all audiovisual evidence of real hardware I've been able to find on YouTube. Only a fraction of the boards featured in YT video uploads have higher-pitched sound, and of those examples, all of them are either described as bootlegs by the uploader, or clearly display a hacked copyright on the title screen.

arknoid2 and clones still have the same sound pitch they've always had, which matches how arkanoid/arkatour sounded pre-0.184.

MAMEinfo.dat for 0.184 notes the following, could this relate to the cause of the change?

- AY-3-8910 sound
. Added a write handler for the case of bc1=a0 and bc2=a1. Added guide to bus control signals.
. Overrided device method to support changing clock frequencies in the AY8910. Added virtual keyword to declaration.
再現手順 
追加情報While logging this bug, I viewed 32 unique YouTube videos (i.e., no two of the same board) of gameplay on actual Arkanoid/Tournament Arkanoid hardware, from the U.S., Japan, Europe or elsewhere, both official and bootleg. Of those, I only encountered five videos that have the 2x higher pitch currently heard in MAME. Three of them clearly display hacked "Tayto", "Game" or "Beta" copyrights, the fourth was described as a bootleg by the uploader, and the fifth was a Tournament Arkanoid that a commenter suggested was likely a bootleg because the sound was the wrong pitch.
