I Can't Adjust My Sony Walkman's Volume

Volume Limit

Sony Walkman MP3 players come with an Automatic Volume Limiter System feature that allows you to set restrictions on volume adjustments. According to Sony, the feature is designed to allow music and videos to sound at a reasonable and comfortable volume level that won't distort sound output. When enabled, this feature is only applied when you're using headphones. It's not supported by the built-in speaker. If you're unable to adjust your Sony Walkman media player's volume, select “Settings” from the home screen to bring up your player's settings. From there, select “Common Settings” and select “AVLS.' Selecting the “Off” option disables the volume limit automatically. Once disabled, pressing the volume up or volume down buttons increases or decreases volume.

Charging

According to Sony, Sony Walkman media players experience sound problems if the device's battery is low. These problems are especially common if you're using the built-in speaker. If a 'Low Battery' warning message appears on your player's screen, connect the player to the computer using the USB cable. It might take up to five minutes for the player to begin charging. This is common for player's that haven't been used for a long period. If you're using a laptop, disable sleep, hibernation or standby mode, or the player won't charge. It takes about 2.5 hours for the Walkman to fully charge. Disconnect the player when you see the 'Full' message on the screen.

Updating Firmware

Updating your Sony Walkman media player's firmware installs the latest features and components that improve your device's performance. If you're still unable to adjust volume, download the firmware update from Sony's website. After downloading the firmware, connect your player to the computer using the USB cable; follow the guided instructions on the download to install the firmware update on your media player safely without damaging or deleting saved content.
