我刚刚为正在构建的媒体 PC 买了一个 WinTV-HVR-5525。但出于某种原因，我似乎无法让该卡在 Ubuntu 22.04 LTS 下工作。我按照 [此处][1] 的说明操作，可以让 DVB-T 和 DVB-C 调谐器工作。但是，该卡还带有卫星调谐器，无论如何我似乎都无法使其工作。我在 /lib/firmware 下安装了固件文件，但不知何故调谐器无法被识别。事实上，甚至连卡本身也无法被识别，直到我在 /etc/modeprobe.d 下创建了一个 .conf 文件，告诉系统它正在使用什么卡：
options cx23885 card=52
因为否则什么都不会发生，在 dmesg 下它只会说
未知 hauppauge 模型 #150339
现在 dmesg 的输出如下所示（删除任何不重要的内容）：

对我来说有趣的是它似乎使用了错误的驱动程序？；
[7.451504] m88ds3103 7-0069: 未知设备。Chip_id=71
根据我能找到的所有来源，它实际上应该是 M88RS6000 调谐器，而不是 M88DS3103。我从其他人那里找到了正确的模块加载的输出：
cx23885: cx23885_dvb_register() allocating 1 frontend(s)

cx23885: cx23885_dev_checkrevision() Hardware revision = 0xd0
所以它似乎无法被正确识别？有人知道如何解决这个问题吗？我也需要卫星功能，所以我现在有点不知所措。任何帮助都将不胜感激！
答案1
由于我使用同一张卡时也遇到了同样的问题（我的是修订版 C5I6），因此我也对解决方案感兴趣。到目前为止，我发现该卡有多个修订版，将 eeprom 型号从 150329 更改为 150339。由于 cx23885 中未找到此新型号 ID，因此无法进行自动检测，您需要 modeprobe.d 文件。此外，cx23885 中的子系统从 0070:f038 变为 0070:f039 遗憾的是，m88ds3103 的芯片 ID 似乎也从 64 更改为 71，这可能是 m88rs6000t 未加载的原因。在 linuxtv.org 的此卡摘录中，您可以看到旧值：

为了使此卡的卫星部分正常工作，我猜测 cx23885 和/或 m88ds3103 需要使用当前型号 ID (150339) 和子系统 (0070:f039) 以及此 WinTV-HVR-5525 修订版的 Chip_id (71) 进行更新。如果有人知道可以将这些值转发给谁，以便更新这些内核文件，请告诉我们。Hauppauge 还更新了他们的 WIN 软件，以使这些修订版正常工作，您可以在更改日志 WinTV v10.0.41115 中看到 https://www.hauppauge.com/pages/support/wintv10_release_notes.html
