arecord 创建的多个文件 [英] Multiple files created by arecord

问题描述

我使用 buildroot 制作了自定义发行版，并为 ARMv7 处理器提供了硬流程.一切正常，除了......

I've made custom distribution using buildroot, with hard-flow for ARMv7 processor. Everything is working except....

# arecord -D hw:0,0 -fdat -d 5 test.wav

这会生成多个文件.数以千计.

This makes multiple files. Thousands of them.

-rw-r--r--    1 root     root        958508 Jan  1 00:19 test-01.wav
-rw-r--r--    1 root     root            44 Jan  1 00:19 test-02.wav
-rw-r--r--    1 root     root            44 Jan  1 00:19 test-03.wav
-rw-r--r--    1 root     root            44 Jan  1 00:19 test-04.wav
-rw-r--r--    1 root     root            44 Jan  1 00:19 test-05.wav
-rw-r--r--    1 root     root            44 Jan  1 00:19 test-06.wav
-rw-r--r--    1 root     root            44 Jan  1 00:19 test-07.wav
-rw-r--r--    1 root     root            44 Jan  1 00:19 test-08.wav
-rw-r--r--    1 root     root            44 Jan  1 00:19 test-09.wav
-rw-r--r--    1 root     root            44 Jan  1 00:19 test-10.wav
-rw-r--r--    1 root     root            44 Jan  1 00:19 test-100.wav
-rw-r--r--    1 root     root            44 Jan  1 00:19 test-101.wav
-rw-r--r--    1 root     root            44 Jan  1 00:19 test-102.wav
-rw-r--r--    1 root     root            44 Jan  1 00:19 test-103.wav
-rw-r--r--    1 root     root            44 Jan  1 00:19 test-104.wav
-rw-r--r--    1 root     root            44 Jan  1 00:19 test-105.wav
-rw-r--r--    1 root     root            44 Jan  1 00:19 test-106.wav

等等……

如果我传递 -d 参数会发生这种情况.有什么想法吗?

This happens if I pass -d parameter. Any idea?

推荐答案

这个问题似乎出现在1.0.28arecord版本(arecord --version).在运行 Raspbian Jessie 的 Raspberry Pi 3 上，我设法将 alsa-utils 从 1.0.28-1 降级到 1.0.25-4(回滚到 Wheezy 的仓库)，这样就解决了问题:

The problem seems to appear on ARM architecture starting from 1.0.28 arecord version (arecord --version). On Raspberry Pi 3 running Raspbian Jessie I managed to downgrade alsa-utils from 1.0.28-1 to 1.0.25-4 (rolling back to Wheezy's repo), so that fixed the problem:

• sudo nano/etc/apt/sources.list
• 将以下行添加到文件末尾deb http://mirrordirector.raspbian.org/raspbian/wheezy main contrib non-free rpi
• sudo apt-get update
• sudo aptitude versions alsa-utils(这应该显示旧版本可用)
• sudo apt-get install alsa-utils=1.0.25-4
• 现在 arecord --version 应该显示降级的版本 1.0.25
• 您现在可能想要删除添加到/etc/apt/sources.list 的那一行，这样您就不会从 wheezy 获得其他包
• sudo nano/etc/apt/sources.list
• 删除行 deb http://mirrordirector.raspbian.org/raspbian/wheezy main contrib non-free rpi
• 再次运行 apt-get update
• 另外，将 alsa-utils 搁置，以免升级
• sudo apt-mark 持有 alsa-utils

• sudo nano /etc/apt/sources.list
• add the following line to the end of the file deb http://mirrordirector.raspbian.org/raspbian/ wheezy main contrib non-free rpi
• sudo apt-get update
• sudo aptitude versions alsa-utils (this should show the old version to become available)
• sudo apt-get install alsa-utils=1.0.25-4
• now arecord --version should display downgraded version 1.0.25
• You probably now want to remove that line you added to /etc/apt/sources.list, so that you don't get other packages from wheezy
• sudo nano /etc/apt/sources.list
• remove the line deb http://mirrordirector.raspbian.org/raspbian/ wheezy main contrib non-free rpi
• run apt-get update again
• also, put alsa-utils on hold so it doesn't get upgraded
• sudo apt-mark hold alsa-utils
