Dual-booting is the act of installing two operating systems on one computer, with a user choosing which OS to boot into upon startup. While this can be a convenient way to access multiple operating systems on one device, it can also cause issues with audio output. Users have reported problems with sound when switching between operating systems, with audio cutting out or becoming distorted. This issue has been observed across various operating systems, including Windows, Linux, Ubuntu, and Hackintosh. While there are some suggested workarounds, such as adjusting volume settings, updating kernel versions, or using HDMI audio output, a complete fix for the issue is yet to be found.

What You'll Learn
Linux/Windows dual boot audio problem
When dual-booting Linux and Windows, users have reported issues with sound output. These issues include no sound, distorted sound, and popping and crackling noises. The problem appears to occur when switching between the two operating systems, particularly after booting into a different OS than previously.
One possible solution to this problem is to put the computer to sleep and then wake it up. This has been reported to work for both Ubuntu and Windows. Another solution is to disable Windows Fast Startup or Windows 10 fast boot, which has been known to cause issues with sound output when dual-booting.
For those dual-booting Ubuntu and Windows, modifying the alsa-base.conf file or updating the kernel version has been suggested as a fix. Additionally, checking the output volume settings and ensuring they are not set to a minimum can help resolve audio issues.
In some cases, the problem may be related to the sound card. Upgrading the sound card to a USB audio device that is compatible with both Mac and Windows can help resolve the issue. Alternatively, switching the audio output to HDMI may also work.
When switching from Linux to Windows, it is recommended to do a full shutdown and then boot into Windows, as simply restarting may cause audio issues. This suggests that Linux may interfere with the laptop's power settings or cause issues with firmware loading on the sound card.

Sound issues with hackintosh
Dual booting Windows and Linux can cause audio issues, with some users reporting that sound only works properly when they boot directly into Windows. In some cases, the audio becomes distorted or completely disabled when switching between operating systems.
Similar issues have been reported by Hackintosh users, who have experienced sound problems when dual booting with Windows. One user reported that their Realtek audio stopped working when rebooting from Windows to their Hackintosh, with sound only functioning through HDMI. Another user suggested upgrading the sound card or using a USB audio device that is compatible with both Mac and Windows to avoid these issues.
There are several potential workarounds for the sound issues experienced by Hackintosh users:
- Installing an older version of Windows, specifically version 1809, has been suggested as a solution, although this may not be ideal as updates need to be avoided to maintain functionality.
- Completely powering off the computer between OS switches, rather than simply restarting, has been reported to resolve the issue for some users.
- Using the recent beta for AppleALC.kxt has been reported to fix the issue for some users.
- Adjusting the boot arguments by adding "alctcsel=1" or "alcdelay=X" (where X is the number of milliseconds to delay loading, up to 3000) may help mitigate the issue.
- Routing speakers through the monitor and using the GPU's HDMI audio output as a speaker can be a workaround, although it is not an ideal solution.
It is important to note that the specific fixes may vary depending on the hardware and software configurations of the Hackintosh setup. Users are advised to seek further guidance from online communities and forums dedicated to Hackintosh and dual-booting if they continue to experience sound issues.

No sound on Ubuntu/Windows dual-boot
If you are experiencing no sound on Ubuntu after first booting into Windows, there are several potential fixes you can try.
One user reported that the issue was caused by the Output volume being set to a minimum in System Settings. Adjusting the volume to around 80% resolved the issue.
Another user suggested that the problem could be due to Windows Fast Boot. To resolve this, put your computer to sleep, wait for a few seconds, and then wake it up. This forces Windows to shut down properly, allowing Ubuntu to access the speakers.
If you are using AppleALC for audio, you can try adding the "alctcsel=1" boot argument to change the guarded TCSEL to TC0, which can help with audio issues after booting from another OS.
Additionally, some users have reported that the issue only occurs when restarting from one OS to another, and a full shutdown and boot into the desired OS resolves the issue.
If none of the above solutions work, you may need to try updating your kernel version or sound card, or consider using an older version of Windows that is known to work with dual-boot audio.

Low volume on dual boot
Dual-booting can sometimes cause issues with sound output, including low volume. This issue has been observed across various operating systems, such as Linux, Windows, Ubuntu, and Hackintosh.
One possible reason for low volume on dual boot could be the settings of the built-in audio controller. For example, in a Dell PC with Ubuntu and Windows dual-boot, the output volume was initially set to a minimum, resulting in low volume. Adjusting the volume settings in the System Settings resolved this issue.
Another factor could be the specific sound card or driver being used. In some cases, the sound card may not be compatible with both operating systems, leading to low volume or audio issues. For instance, a user reported that their Xonar Phoebus sound card had low volume even at 100% after dual-booting with Windows.
Additionally, the ALSA sound level settings could be a potential cause for low volume. ALSA has two main volume settings: PCM and Master. Users have reported that adjusting these settings, either through the desktop GUI or terminal, helped resolve low volume issues on dual boot.
Furthermore, the way the operating systems are booted can impact sound output. Some users have found that completely powering off the system between OS switches, rather than just restarting, helped resolve audio issues on dual boot.
In certain cases, the issue may be specific to a particular operating system. For instance, a user reported low volume on Windows 10 after dual-booting with Ubuntu, with maximum volume being far lower than before. This could be related to how Windows interacts with the sound driver during the boot process.
To troubleshoot low volume on dual boot, users can try the following steps:
- Check and adjust the output volume settings in the System Settings or audio controller settings.
- Ensure that the sound card and drivers are compatible with both operating systems and update them if necessary.
- Verify and modify the ALSA sound level settings, including PCM and Master, through the desktop GUI or terminal.
- Try completely powering off the system instead of just restarting when switching between operating systems.
- Refer to specific troubleshooting guides for the operating systems in use, as there may be unique solutions for each OS.
