ATAPI: audio CD stops playing (2.2.17 & 2.4.0-test?)

ATAPI: audio CD stops playing (2.2.17 & 2.4.0-test?)

[Stanislav Brabec]

Description:
On 2.4.0-pre9 and 2.4.0-pre10:
Playing of some audio CD's stops in nearly regular places. Also pressing >> in CD software
panel in nearly all cases ends by stop.

All these stops are reported:
Nov  3 21:41:47 utx kernel: ATAPI device hdb:

On 2.2.17:
Rejects to play audio CD on this hardware at all with report:

- play CD audio correctly, don't stop after 12 minutes.

Patch in 2.4.0-test12 really fixes this problem.

But problem with >> (fast forward playng of short samples) still remains
on some audio CD's.

This is the same case that Miles reported, it's very odd how that 8th
byte gets screwed somehow... But I know about this, I just haven't tracked
this down yet.

At least Stanislav's problem is a userland problem. Sometimes tcd/gtcd
(the software Stanislav uses to play CDs) miscalculates frame values. A
patch to tcd is available at http://bugs.gnome.org/db/33/33600.html.

Norbert

Ah interesting, I _bet_ this is also what everybody else is seeing!

I have tested this patch and there is my result:


Linux kernel patch solves the problem of stopping while playing after
2min 40sec.

gnome-media/tcd/linux-cdrom.c with fix http://bugs.gnome.org/db/33/33600.html
solves the problem of fast-fwd. Even on older kernels ffwd works OK.

Both these were two independent bugs, one in kernel, second in tcd.


I have looked into GNOME CVS and nobody have yet comitted this patch
into CVS, so I am doing it.

Can anybody close the bug in GNOME bug tracking system?
