Summary	08955: cdimono1 [zeldgamu]: Game hangs during shopkeeper cutscene
Description	There is the shopkeeper in Sakado. If you talk to him repeatedly, after about 20 times, the game will hang while exiting the "cause I'm on your side" cutscene and returning to gameplay. I've selected "Always" as reproducibility as within a duration of maximum one minute, this can be reproduced always. When colleting CDIC verbose information: [:cdic] ':maincpu' (0042A46E): cdic_w: Data Buffer Register = c000 & ffff [:cdic] ':maincpu' (0042A46E): cdic_w: Data Buffer high-bit set, beginning command processing [:cdic] ':maincpu' (0042A46E): cdic_w: Update command [:cdic] ':maincpu' (0042A472): cdic_r: Data buffer Register = 4000 & ffff [:cdic] ':maincpu' (0042A476): cdic_r: X-Buffer Register = 0000 & ffff [:cdic] ':maincpu' (0042A476): Clearing CDIC interrupt line [:cdic] Audio sector counter 10, deducting and skipping [:cdic] About to process a disc sector [:cdic] Disc sector, current LBA: 00023633, MSF: 32 12 47 [:cdic] Sector header data: 00 ff ff ff ff ff ff ff ff ff ff 00 32 12 47 02 01 01 48 00 01 01 48 00 [:cdic] Mode 2 sector is selected due to channel (register 0003, buffer channel 0001) [:cdic] Audio is not selected; submode 48 [:cdic] ':maincpu' (0042ACEE): cdic_r: Data buffer Register = 4001 & ffff [:cdic] ':maincpu' (0042ACEE): cdic_w: Data Buffer Register = 0001 & ffff [:cdic] ':maincpu' (0042B058): cdic_r: Data buffer Register = 0001 & ffff [:cdic] ':maincpu' (0042B074): cdic_r: Z-Buffer Register Read: 2801 & ffff [:cdic] ':maincpu' (0042B084): cdic_r: Audio Buffer Register = 0000 & ffff [:cdic] ':maincpu' (0042B058): cdic_r: Data buffer Register = 0001 & ffff [:cdic] ':maincpu' (0042B074): cdic_r: Z-Buffer Register Read: 2800 & ffff [:cdic] ':maincpu' (0042B084): cdic_r: Audio Buffer Register = 0000 & ffff [:cdic] ':maincpu' (0042B058): cdic_r: Data buffer Register = 0001 & ffff [:cdic] ':maincpu' (0042B074): cdic_r: Z-Buffer Register Read: 2801 & ffff Afterwards this repeats. The game never continues.
Steps To Reproduce	Start the game, when seening the map, select Sakado in the East of the island. Enter the first door. Hit the old person repeatedly and close the cutscene and random times to cause the issue. The game will hang on the current screen of the cutscene
Additional Information	I wasn't sure whether this is a bug in the game, so I tried to reproduce it on a 210/20 and on cdiemu but the bug didn't occur.

No.22448 Slamy Tester 3 days ago	This issue might actually be related to https://mametesters.org/view.php?id=8833 Both are sound issues. I'm currently thinking about creating a PR. src/mame/philips/cdicdic.cpp: - m_audio_sector_counter = m_audio_format_sectors; + m_audio_sector_counter = 0; It seems that after disabling the audiomap, the current code does one extra round. This might be not correct. I'm not yet 100% sure.
