Question about Casio Cassiopeia E-125 Pocket PC
I'm hearing a click coming from the speaker in my E125 at the beginning of sound events or at the very beginning of audio playback. Just happens for a moment, but sounds like a power surge to the speaker prior to playback. Any ideas how to remedy this?

Solution to CF Recorder Click Noise Problem! Hi, ever since I got my Netbook, I was annoyed about the click noise, most Netbook users hear, when recording straight to a Compact Flash Disk. Problem To test if you are suffering from this problem, make the following test: 1. Make sure you have a CF disk in D: (or E: ) 2. Start the Recorder application. 3. Select File/New File and enter any name using the drive the CF is in (D or E) 4. Make a recording, for about 10 seconds, preferably in a quiet room without saying anything. 5. Playback the recording. You will hear a clicking sound often about once every second (varies according to CF-Card used)! 6. If you hear no clicking sound and the recording sounds clean, you have no problem! Solution I have just spent a couple of days at Photokina (the world's largest photographic trade fair currently on in Cologne, Germany) visiting CF-Manufacturers with my Netbook to get to the bottom of the problem. Basically, the problem is caused by the buffer in the CF-Controller emptying faster than it is being supplied with data. This affects a lot of CF card manufacturers and the only solution (apart from recording on C) is to use a CF card with an Hitachi Controller as that is the only controller which takes account of this problem and handles the data stream correctly. I tested a number of CF-Cards at the show (only Dane-Elec refused to let me test their card) and this is the result of my hard work: CF-Cards that Work Correctly: SimpleTech (all SimpleTech CF-Cards use the Hitachi Controller) Casio (Hitachi Controller) Hitachi (of course) DataFab (the sample I tested worked, they did not know which controller) Extrememory (Some work, some do not) Note: Large CF-Cards can still have problems. Even the SimpleTech 512MB CF-Card produced the click noise whereas the 256MB card was OK! CF-Cards with Click Problem: Sandisk (incl. Ultra) Toshiba (all 3 controllers tested) Dane-Elec (not tested, but uses Toshiba controller) Those were the cards I tested. Perhaps the members of this forum can post their findings on other makes not mentioned above. I personally made the mistake of buying a Toshiba card and had no end of problems. I must say that the people at Toshiba were very helpful and let me test a range of their cards. I will now be returning my Toshiba card and ordering a CF-Card from Simpletech as the cards I tested worked well. I have no connection with any of these card manufacturers! However, I do recommend that before buying a CF card for the Netbook, from any manufacturer, you should always do the above test, first! Remember, in most cases I could only test 1 card per manufacturer so each card could differ. Test before you buy is very important in this case! I hope this helps!

Tips for a great answer:
If the playback device is built into the motherboard, the device may not be enabled in the BIOS. Check your BIOS settings. If your sound device is disabled, enable it and repeat this procedure.
If your playback device (AC97 Audio) is enabled you may require a driver update and it's time to seek some professional help from a qualified PC Technician.
