Phasor card issue with SKYFOX PITFALL II

[PaulLouviers]

Hi,

With TTREPLAY V5.3 and other previous release, I get no sound only for Two Games :
SKYFOX > only classic speakers sound
PITFALL > nothing.

My set up : IIE PAL +(ENH) + 128K°+ VidHD + BooTI

For other games that are compatible with soundcard
8bit-Slicks
Apple Cider Spider
Berzap
Bouncing Kamungas
Flak
Lancaster
Thunder Bombs
Willy Byte
Zaxxon
Zoo Master
Ultima IV & V.

Any idea to do a troubleshooting is welcome !

Paul.

The two failing games require stereo support. If the second speaker is broken somehow then there will be no sound.
Does Battle Cruiser have MB sounds? It also requires stereo support. If it has no sound then I suspect an issue with your card.
Meanwhile, I will update TR to report if it finds mono or stereo, which could help.

@PaulLouviers: ...or perhaps the Phasor card is faulty?

You can try mb-audit to identify any faults.
Download the .dsk here.

Hi Guy, Battle cruiser has also the same problem on my system no sound at all ... for the moment I am not able to run Mb-audit. I have only a booti card, which support only prodos ...

If you have any other software to do a diagnostic, I will appreciate.

I miss to tell you that the speakers are in a good shape and fully operational, For ultima V the sound is on two speakers, for 'ONE on One" the initial music is on two speakers, for Lancaster the music is on the two speakers in Stereo, but most of games on total replay V5B3 (with music) are only on one speakers (A or B, it depends).

Pitfall and skyfox are KO.

To be honnest it is weird, Because I tri the following demonstration and the two speakers are ok in stereo LATECOMERE

Here's mb-audit v0.9 on a ProDOS image:

Hi, I get this result $00 = 1 in slot 4 $80 nothing SP nothing 65C02 detected.

Thanks. This confirms that the second channel is not responding, which is why you have no sounds in the games that require both channels. It's a hardware issue.

@PaulLouviers - as Peter says: it's a hardware issue.
If you want to raise a new issue over in https://github.com/tomcw/mb-audit, then we can iterate and try to pinpoint whether it's a 6522, a AY8913 or something else.
