Subject: bug in playing 6-channel sound
Date: Thu, 4 Jul 2019 11:46:20 +0100 [thread overview]
Message-ID: <23837.55548.631053.741245@vis.stevens-bradfield.com> (raw)
Some five years ago, the following post
https://mailman.alsa-project.org/pipermail/alsa-devel/2014-February/072265.html
reported a failure to play six-channel sound, that could be worked
around by setting the prealloc value for the device to various values
*other than* the default 64.
I have just run into this playing a movie from my laptop (Thinkpad
Yoga X1, Intel HDA PCH sound card outputting through HDMI) running
Xubuntu 18.04, up to date as at the time of posting.
I see exactly the same problem as in that post, and the same
workaround works for me - I tried prealloc values 63,65,32,128, and
any of them is ok.
I'm a bit baffled that such a problem has survived for several years.
If any developer would like me to provide debugging information,
please get in touch - I have some time available at present, but not
enough to learn ALSA and debug it myself!
I will remain subscribed to the list for a few weeks to read any
followups.
