我有一个HP EliteBook 8560w带有 Kubuntu 14.04 和 3.13.0-30 内核。
声音不起作用。我尝试
- 升级系统
- 重新安装 pulseaudio
- 添加
options snd-hda-intel model=auto/etc/modprobe.d/alsa-base.conf
在启动时我收到以下错误：
genirq: Flags mismatch irq 5. 00000080 (snd_hda_intel) vs. 00000000 (parport0)
hda-intel: unable to grab IRQ 5, disabling device
的输出aplay -l是

没有硬件问题，声音在 Windows 中工作正常。有什么想法吗？
答案1
您添加的驱动程序/etc/modprobe.d/alsa-base.conf适用于英特尔声卡。这在你的系统上不起作用是完全正常的，因为声音芯片的制造商NVidia. 您的计算机因此禁用该设备：
genirq: Flags mismatch irq 5. 00000080 (snd_hda_intel) vs. 00000000 (parport0)
hda-intel: unable to grab IRQ 5, disabling device
您的播放设备列表还会显示NVidia硬件。
您需要找到并使用适合您的NVidia平台。
