This message is from the application that generates text voice messages using SAPI4 voices. This application works perfectly under wine launched in 32 bit linux.

I've upgraded wine to version wine 1.7.18 (Arch Linux).
I still receive the message: "Audio Reset Failed: Access violation at address 7BC4D272 in module 'ntdll.dll'. Write of address F82A011C"

This time I've run wine with the following debug channels: +tid,+mmdevapi,+winmm,+driver,+msacm,+midi,+dsound,+dsound3d,+dmusic,+mci,+oss,+alsa,+coreaudio.

I've attached the log.
Please write me if I can provide anything else.

Great thanks for your help.
