China DOS Union

A few days ago, I heard that the latest version of MPXPlay already supports the soft sound card on Intel motherboards. I downloaded it and tried it, and indeed it could correctly recognize my Intel AC97 soft sound card. I opened an MP3 file and played it. Everything was normal except there was no sound. Fortunately, my PC also has an operating system called Windows, heh heh. Since there was no sound, I went to listen to songs under Windows 3.1.

Haha, an interesting thing happened. When I exited from Windows 3.1 to DOS and then used MPXPlay to play a song, there was actually sound. I tried several more times, and as long as my DOS had once entered Windows 3.1, MPXPlay would have sound when playing music. So now when I listen to songs under DOS, I always enter Windows 3.1 first, then exit, and then use MPXPlay.

I haven't tried Windows 98. Those interested can try whether there will be sound when using MPXPlay to play songs after returning from Windows 98 to DOS.

I wonder why this is. Could it be that the sound card driver under Windows has triggered some nerve in DOS?

Hehe, you can give this ICHINIT a try. It's an initialization program for Intel AC97 sound cards. Run it first and then run MPXPLAY to see if there's sound:

Although I can't test it now, I think that initialization program must be okay.

Heh, can we test now? If it really can, then this problem will be completely solved.

Still no conditions to test.
But I think this program must work. When I just discovered this phenomenon, I felt it should be that the driver under win wakes up the sound card, and after looking at the readme in this initialization program, I am more convinced of this point.

It has been tried, and it is completely okay! ～

It can be seen that most AC97 sound cards can already be supported under DOS currently. Not only WAV, MP3, OGG and other formats, but also the music in WMV and AVI can be played!

Yeah, the music in wmv and avi can both be listened to.
But I also found a problem,
that is, this initialization program will prompt illegal parameters when run under msdos6.22 without parameters, I can only enter something like "ichinit /MO:22" with any parameter to make it work.
While there is no such phenomenon under ms-dos 7.1, just enter ichinit.
I really don't understand, people made the ich player and ich initialization program, why is there no one making the driver???

Hehe, last time we originally planned to make a driver, but due to the lack of relevant information, we finally gave up and only made a WAV player. However, it is really not easy to make the SB virtual driver for the Intel ICH AC97 sound card. Because the Intel ICH AC97 sound card is different from ordinary PCI sound cards and some VIA AC97 sound cards, there is not enough hardware support (similar to WinModem, that is, software modem), so it is estimated that because it is relatively difficult to make a driver, its company did not provide a driver, and no one else made it either. But now there are both the player (it's a pity that the current MPXPLAY does not support the SiS7012 AC97 sound card) and the initialization program, so we should already be grateful.

As for the ICHINIT parameter issue, it can be explained that the compatibility of MS-DOS 7.1 is the best, and the new version is stronger than the old version.

Yeah, there was a lively discussion in the programming section at that time, and then a WAV player came out. I even used it, but it couldn't adjust the volume. Hehe. As for the support of the player, it's really fortunate, but the biggest shortcoming without drivers is that I have to play DOS games in Windows.

It should be able to adjust the volume. You can increase/decrease the volume using +/-. There is also corresponding display in the "Vol:" below.

Really? I forgot, heh heh, it was two years ago.
The one I used was the most original, the one that just came out. Later, because it only supported wav, it was really inconvenient, and I had to convert mp3 to wav to listen. So I haven't tried the new version either.

I also discovered this problem. I was afraid that some people would have trouble testing, so in the later versions of WPLAY, a piece of 44kHz WAV music is included by default.

Where can I download it? I also want to try it. You can also send one to me: chujiafu@126.com
