Bug#534797: contradictory advice when checking for sound issues
Package: release-notes
Severity: normal
Tags: patch
Hello,
In the "Sound stops working" section, the "alsa checklist" says:
- make sure on OSS modules are loaded
....
- check whether the command 'cat /dev/urandom > /dev/dsp' works for root
This is contradictory because /dev/dsp does not exist unless you have
either the OSS modules loaded or the alsa-oss compatibility layer
installed.
Attached a patch to replace this with the 'speaker-test' command. I
could commit it directly if it's easier for you.
Regards,
Andrei

Subject: [PATCH] patch to use speaker-test instead of cat /dev/urandom > /dev/dsp
this is needed because previously it is recommended to not have any oss
modules loaded, but /dev/dsp does not exist if oss (or the alsa-oss
compatibility layer) is not installed.
