Title:
snd-hda-intel needs machine-specific flags sometimes
Status in Puredyne Documentation:
Won't Fix

Control: I/O- Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr-
Stepping- SERR- FastB2B- DisINTx-
Status: Cap+ 66MHz- UDF- FastB2B- ParErr- DEVSEL=fast >TAbort-
<TAbort- <MAbort- >SERR- <PERR- INTx-
Latency: 0, Cache Line Size: 64 bytes

dmesg:
[ 40.597010] hda-intel: azx_get_response timeout, switching to polling

mplayer with alsa output:
audio is incredibly quiet even with everything turned up in alsamixer
mplayer freezes at end of playback
jackd:
jackd watchdog: timeout - killing jackd (after about 6 seconds from launch)
there are workarounds with kernel and module settings (boot-time
flags, no recompilation necessary), but different machines may have
different workarounds...
