Arch Linux 根本不播放声音

无论我做什么，我的 Arch Linux 安装都拒绝播放声音。我已经运行了aplay -l，它正在识别我的声卡。这是输出：

**** List of PLAYBACK Hardware Devices ****
card 0: Generic [HD-Audio Generic], device 3: HDMI 0 [HDMI 0]
Subdevices: 1/1
Subdevice #0: subdevice #0
card 0: Generic [HD-Audio Generic], device 7: HDMI 1 [HDMI 1]
Subdevices: 1/1
Subdevice #0: subdevice #0
card 1: Generic_1 [HD-Audio Generic], device 0: ALC245 Analog [ALC245 Analog]
Subdevices: 1/1
Subdevice #0: subdevice #0

这是输出lspci -k：

Usage: lspci [<switches>]

Basic display modes:
-mm             Produce machine-readable output (single -m for an obsolete format)
-t              Show bus tree

Display options:
-v              Be verbose (-vv or -vvv for higher verbosity)
-k              Show kernel drivers handling each device
-x              Show hex-dump of the standard part of the config space
-xxx            Show hex-dump of the whole config space (dangerous; root only)
-xxxx           Show hex-dump of the 4096-byte extended config space (root only)
-b              Bus-centric view (addresses and IRQ's as seen by the bus)
-D              Always show domain numbers
-P              Display bridge path in addition to bus and device number
-PP             Display bus path in addition to bus and device number

Resolving of device ID's to names:
-n              Show numeric ID's
-nn             Show both textual and numeric ID's (names & numbers)
-q              Query the PCI ID database for unknown ID's via DNS
-qq             As above, but re-query locally cached entries
-Q              Query the PCI ID database for all ID's via DNS

Selection of devices:
-s [[[[<domain>]:]<bus>]:][<slot>][.[<func>]]   Show only devices in selected slots
-d [<vendor>]:[<device>][:<class>]              Show only devices with specified ID's

Other options:
-i <file>       Use specified ID database instead of /usr/share/hwdata/pci.ids
-p <file>       Look up kernel modules in a given file instead of default modules.pcimap
-M              Enable `bus mapping' mode (dangerous; root only)

PCI access options:
-A <method>     Use the specified PCI access method (see `-A help' for a list)
-O <par>=<val>  Set PCI access parameter (see `-O help' for a list)
-G              Enable PCI access debugging
-H <mode>       Use direct hardware access (<mode> = 1 or 2)
-F <file>       Read PCI configuration dump from a given file

这是输出sudo alsactl init

奇怪的是，声卡似乎是 HDMI，所以也许这就是问题所在？

这是一台 HP Envy x360，除了这个小问题之外，它运行良好。我希望能够播放声音，并且非常感谢解决这个问题的任何帮助。谢谢！

我发现了以下内容ubuntu 论坛上的帖子其中OP描述了相同的问题并且也具有相同的ATI R6XX HDMI设备。解决方案是radeon.audio=1通过执行以下操作来设置内核标志：

  1. /etc/default/grub使用文本编辑器打开

  2. 找到条目GRUB_CMDLINE_LINUX_DEFAULT

  3. 添加radeon.audio=1在双引号部分的末尾

  4. 保存文件并运行sudo update-grub

例如：

更改原始/etc/default/grub条目：

GRUB_CMDLINE_LINUX_DEFAULT="loglevel=3 quiet"

到：

GRUB_CMDLINE_LINUX_DEFAULT="loglevel=3 quiet radeon.audio=1"

请勿/boot/grub/grub.cfg按照该线程中一位用户的指示进行编辑。

如果这不起作用，或者radeon.audio=1已经设置，请报告您进入alsamixer并按时列出了哪些设备F6？按F6alsamixer 应该允许您选择系统识别的卡。

我的猜测是 ALSA 默认使用 HDMI 输出声音。您可以通过将笔记本电脑插入带有 HDMI 的电视来测试这一点。

您还可以尝试强制 aplay 通过其他声音设备输出作为测试：aplay -Dhw:1,0 /usr/share/sounds/alsa/Noise.wav。如果可行，您可以使用此处的说明将卡 1 设置为默认值：https://www.alsa-project.org/main/index.php/Setting_the_default_device。
