AP192 Bugs - Driver 126.96.36.19957, Win XP
The latest driver for the Audiophile 192 under Windows XP has a handful of severe bugs.
The driver is dated 1/9/2006 in Control Panel, so it would be great if we could get an update that addressed these issues. The software team's focus may be on Windows 7, but Windows XP is still used heavily enough that it cannot be considered an obsolete operating system. Forcing users to upgrade to Windows 7 just to run an up-to-date audio driver is pretty harsh.
Having said that, I don't know if the Windows 7 driver has these same issues.
- The driver does not support multiple applications well. Symptoms:
- Adjusting the volume of one application often changes the volume of other applications.
- Closing one application often disables sound completely in other running applications.
- When one application's sound fails (see below), it affects all other running applications.
- The sound driver completely fails (crashes?) frequently. Symptoms:
- Sound simply stops working in all running applications. Closing and restarting usually fixes temporarily.
- Cakewalk will display the message "The audio engine has stopped unexpectedly."
- Some applications, e.g. WinAmp, will freeze when attempting to start playing.
- General application incompatibility. Some less common applications crash or completely fail to run. These applications generally work on any other generic sound card. One example is VST Host. Another is "AP Tuner," which only runs normally if it is the only application using sound.
- Noise when no audio is played. This seems to happen most often when an application that plays audio is running, but not actively playing any audio. A good example is Firefox. Viewing a website that plays audio (e.g. Pandora, SiriusXM) and pausing the audio will almost always reproduce this problem.
- Garbled sound. Roughly 5% of the time, audio is completely garbled in all applications. Cakewalk reproduces this most easily. Record some audio and simply play it back repeatedly. Randomly, about 1 in 20 playbacks will be garbled. It's possible that using high-quality audio makes this problem more frequent (I tested using 24 bit, 96KHz), but the problem can be observed at any quality level, in any application.
These problems are severe enough that the card is essentially unusable. Six years without a driver update is a really long time. If I hadn't thrown away the packaging, I would absolutely have returned this card by now. I'm faced now with waiting indefinitely for a driver update, or just accepting a $200 total loss. Good hardware is useless without good drivers.
