Summary:                    No sound from speakers
Description: 
Alsa seems to detect the sound card, but when I try to actually play
something there is no sound from the speakers.

Are there any error message in system log when the driver is loaded ? 

dmesg

It seem that es1373 is not able to read/write the codec  LM4548VH

According to datasheet, LM4548 should return

00: 0d50

7c: 4e53
7e: 4300

dmesg output attached.  No obvious errors from the sound driver, but there
are the messages from the tv card driver about parity issues... Not sure
whether that's relevant.
